ETABS stands for Extended Three-Dimensional Analysis of Building Systems. ETABS is commonly used to analyze: Skyscrapers, concrete structures, low and high rise buildings, and portal frame structures. The case study in this paper mainly emphasizes on structural behavior of multi-storey building for different plan configurations like rectangular, C, L and I-shape. Modelling of 15-storeys R.C.C. framed building is done on the ETABS software for analysis ETABS issue, for analysis and design for building systems. ETABS features are contain powerful graphical interface coupled with unmatched modeling, analytical, and design procedures, all integrated using a common database. STAAD and ETABS both of the software are well equipped and very much capable of handling different shape of the structures, static and dynamic loadings and different material properties.

Structural Analysis is a branch which involves in the determination of behaviour of structures so as to predict the responses of different structural components due to impact of loads. ETABS (Extended 3 Dimensional Analysis of Building Systems) is a software which is incorporated with all the major analysis engines that are static, dynamic, linear and non-linear etc. The main purpose of this paper is to design Multi-storeyed building with a static method, since an effective design and construction of earthquake resistant structures are important all over the world. This project deals with seismic effect on “analysis, design and comparison of multi-storey residential building of stilt+17 floors in zone-iii and zone-iv using ETABS”. It is an attempt to study the behaviour of a residential building using ETABS in different zones and areas with same soil bearing capacity. Analysis and design has been carried out as per IS1843-2002 (Part-1) and IS 456:2000. The more drifts and displacements have been noticed in zone 4 compared to zone 3

A multi-storey building is habitually modelled as a frame structure which neglects the shear wall/slab openings along with the inclusion of staircases. Furthermore, the structural strength provided by shear walls and slabs is not precisely incorporated. With increasing building height, the effect of lateral loads on a high-rise structure increases substantially. Inclusion of shear walls and slabs with the frame leads to improved lateral stiffness. Besides, their openings may play imperative role in the structural behaviour of such buildings. In this study, 61 multi-storey building configurations have been modelled. Corresponding analyses are performed to cope with the influence of shear walls, slabs, wall openings, masonry walls and staircases in addition to frame modelling. The finite element approach is used in modelling and analysis. Structural responses in each elemental combination are evaluated through equivalent static and free vibration analyses. The assessment reveals that inclusion of only slab components with frame modelling contributes trivial improvement on structural performance. Conversely, the presence of shear wall slabs with frame improves the performance noticeably. Increasing wall openings decreases the structural responses. Furthermore, it is not recommended to model staircases in addition to frame–slab–shear wall modelling, unless the effect of wall openings and slab openings is adequately considered.

Columns rest on the beam without foundation are called floating column.They are used commonly in multi-storey buildings which are purposed to hold parking at ground floor or open halls at higher floors. Discontinuation within the load transfer path is seen in this column. Thus they are designed for gravity loads. But these structures aren’t designed for earthquake loads.In present scenario structures with floating column may be a common characteristic in urban India. However in tectonic areas, this type of structure is not preferred due to discontinuity of load transfer path i.e. whole earthquake load on the structure is shared by the shear walls without any loads on the floating columns.This paper review the nature of a multi-storey building under quake forces with and without of floating columns. This analysis focus the importance of specially identifying the presence of the floating column within the study of the struture, establish its correlation with the building without a floating column using designing software Extended three dimensional analysis of building systems (ETABS). This paper also discusses the performance of structure having floating column in seismically active areas. Besides these various parameter such as maximum displacement, effect on number of storey on drift, base shear are also studied.

ABSTRACT This study examines the daylight and energy performance of 27 external shading scenarios in a high-rise residential building in the urban tropics. The cooling energy, daytime lighting energy and the spatial daylight autonomy (sDA) of the building model were simulated in Rhino3D and Grasshopper simulation software. The best performance scenario (vertical and horizontal shading on the twentieth floor, horizontal shading only for the eleventh floor and no shading for the second floor) satisfied 75 sDA(300lx|50) with corresponding annual enery performance of 16%–20% in the cardinal directions. The baseline scenario, which is the current practice of providing balconies on all floors, reduced daylight to less than 75 sDA on the eleventh and second floor, even though it had higher annual enery performance (19%–24%) than the best performance scenario. Application of the design principles to a case study indicated that 58% of the spaces had over 75 sDA for both Baseline and Best performance scenarios, while an increase in enery performance of 1%–3% was found in the Best performance scenario compared to the Baseline.

The use of seismic isolation for the seismic rehabilitation of existing buildings is very attractive but often very tricky due to several aspects related to its implementation. In this paper, a case study of seismic rehabilitation of a high-rise residential building with seismic isolation is presented. The building under consideration is located in southern Italy and it is placed next to another building from which it is separated by a gap of 400 mm. In the paper, all the steps of the seismic rehabilitation process are described. First, the target objective of the seismic rehabilitation and the choice of isolation system type and location are discussed. The design of the isolation system, carried out following a direct displacement-based approach, is then examined. Finally, the main phases followed in the installation of the isolation system are described. Some comments on costs and time needed to complete the intervention are also reported.

Abstract Climate change due to architecture occurs as a result of technological developments that support the development of materials, electrical mechanics, structures, and building shapes that play a role in increasing emission levels in the air. One type of building in Indonesia that contributes to increasing emissions is the residential building known as rumah susun. This research employs the case study method, observing the Rumah Susun Jatinegara Barat, located in East Jakarta. The case study shows that the use of prototypes that are not environmentally friendly makes a building’s performance worse. The use of precast, which resulted in monotonous window dimensions, is considered the main factor causing the failure of this Rumah Susun Jatinegara Barat to adapt to the surrounding environment. This problem occurred because the openings in the building façades had a monotonous dimension while the wind intensity that hit the building was increasing. The final result shows that the windows on the façades of the case study were not functioning except if all the openings in the residential unit are open. These results prove that the height of a building is an essential factor in planning high-rise flats, especially in Jakarta.

<p>This study was conducted on the seismic performance of the new DPT 1301/1302 - 61 earthquake design standard in Thailand, the ACI 318-11:2014, and the ASCE 7-16 Standard. The selected sample structure for the case study was an existing five-storey building located in Bangkok. It was designed as a shopping mall having a length of 350 m, a width of 35 m, and a height of 26 m, resulting in a total constructed usable area of 62,000 m2, and consists of shops, restaurants and car-park spaces. Construction started on 15th February 2013, and it was opened on 31st August 2019. Bangkok is situated on a large plain underlain by the thick alluvial and deltaic sediments of the Chao Phraya Basin. The design spectral accelerations, as specified in the previous DPT standard 1302 - 52, were established based on the data of the site characteristics available from the past. However, recent studies have revealed several key features of the site characteristics that are essential for improvement of the previous standard. The structural analysis and design of this building were performed by using computer software programs so as to comply with the previous standard. This paper presents a comparison between the previous and the newly revised standards and examines the design differences by using the selected building as a case study on the structural design of typical existing low-rise buildings in Bangkok.</p>

Pollution Emissions

This report presents an evaluation of emissions from indoor building materials that may cause health damage to the people who occupy the building, since these materials emit toxic chemicals into the air and indoor surfaces. This report presents a case study which evaluates Gypsum Boards, frequently used in the construction of dividing walls and ceilings. The experimental part of this report is based on a three-dimensional space that simulates a common room; for example, a classroom or a workstation. The indoor environmental conditions, such as ventilation, temperature, and humidity, affect chemical emissions from building materials. The technical methodology used, is based on the comparison of conventional materials and alternative materials with similar characteristics and different composition, using similar testing methods, environmental conditions, and instruments and tools. This is a very important report to understand problems related to environmental pollution, specifically of air and its effects indoors, directly on public health, and indirectly on building systems and selection of materials. The tests conclude that alternative materials (with recycled content) are better than traditional ones, because they reduce indoor pollution.

In this paper, a three-dimensional numerical parametric study was conducted to predict the deformation mechanism of a 20-storey building sitting on a (4 × 4) piled raft to an adjacent 25 m deep basement excavation. The influences of different excavation depths were investigated. An advanced hypoplastic sand model (which is capable of taking small-strain stiffness into account) was adopted to capture soil behaviour. The computed results revealed that excavation adjacent to a building resting on the piled raft caused significant settlement, differential settlement, lateral deflection, and interstorey drift in the building. With settlement due to working load (i.e., 4.8dp%), the total settlements of the building (7.8dp%) exceed the maximum allowable foundation settlement (i.e., 50 mm). In addition, substantial bending moment, shear forces, and changes in axial load distribution along pile length were induced. The findings from this study revealed that the building and pile responses are significantly influenced by the excavation depth.

This case study examines the effect of an enclosure retrofit on a high-rise, multi-unit residential building (MURB). Literature on fan pressurization test methodologies and MURB air leakage rates is reviewed. The enclosure for the case study building was tested using the guarded-zone fan pressurization method. Results of the air leakage testing show significant improvement in the enclosure tightness and compare well to measured data for other MURBs across North America. There is recognition of a need to standardize both testing methods and presentation of data for air leakage in MURBs. The issue of abnormal flow exponent values is discussed and recommendations for future research are made.
