Generation is living in a time where in approx. 1.8 million people in India are homeless out of which 52% are based in town. Now a day’s India is heavy populated city in India total 0.15% of the country's total population is homeless. However despite of the explosion in construction activities, the scenario on the housing sector remains far from acceptable. The construction of structure are more composite due to growing human enterprise and the construction industry need to respond to the exceptional challenges presented in front in terms of construction period, economically and durability resulting in affordable residence opportunities for current generation. There is a technology which is capable to overcome the problem the technology is mivan framework technology. Mivan technology is mainly used to construct the tall structures. In this technology we used concrete wall instead of masonry wall. The present paper focuses on the context the use of MIVAN technology for super high rise building and check the seismic response for different shapes i.e. Rectangle Shape, C shape, L shape and I shape of high rise building having irregularity were analyzed by Response spectrum Method using Etab software

Earthquake Load

The advancement of high rise building has been increasing on a large scale. In tall structures shear wall often resisted the lateral load induced by wind and earthquake but as the building height increases the stiffness of the structure reduces. To provide sufficient lateral stiffness of the structure implementation of outrigger system between the shear walls and peripheral columns is often used. The aim of this study is to identify the optimum shape of outrigger belt truss in tall buildings under earthquake load condition. A thirty storey with single belt truss, forty five storeys with two belt trusses and sixty storey with three belt trusses structure was investigated with three different shape outrigger belt truss that is X, V and N. The optimum location by providing single belt truss at 10th story, 15th story and at top story in thirty story building is considered in the analysis. From the analysis a comparative study are made with and without variation of shape of outrigger with belt truss with parameters likes storey displacement and storey drift under earthquake loading and get a optimum position of outrigger belt truss for thirty storey building with single belt trusses placing at different locations.

Reinforced Concrete Wall

Buildings are generally designed to withstand against gravity load for expected life and resist extent of lateral loads by satisfying the codal provision. Main objective of structural elements is to transfer the load safely to the ground, which depends on structural system adopted. Generally, structural system can be adopted depending on the demand of client/building needs/use of structure, environmental condition, performance optimization, economic condition etc. For high rise building moment resisting frame system, structural wall systems, dual system, flat slab-structural wall systems can be employed. A residential ground with ten upper floors high rise building situated in zone-III has been taken under reference, where MRF with RC structural wall system is used. Structural parameters are compared in the study for various location and orientation of RC wall. Linear static and dynamic analysis is performed on the structure based on the IS 1893 Part-I on ETABS software.

In this paper, the optimum or suitable location of shear wall in a high rise irregular shaped building is determined. The criteria of choosing suitable location are well mentioned with suitable examples. We have tested several models in dynamic analysis with the help of ETABS ver. 16. Both Time History and Response Spectrum Methods are performed in the analysis. The paper clearly specifies the causes of torsion in a high rise building as well as it also specifies the ways in which we can control the torsion and storey displacement with the help of shear wall in the high rise buildings.

Based on seismic records with large long-period components at home and abroad, carried on uniform error correction processing and rough site classification, then, used numerical analysis software-MATLAB to calculate the average response spectrum of different types of venues, and used the least square method to do sub-fitting for them, got the long-period quasi-regulatory response spectrums of all kinds of venues; using the general-purpose finite element analysis software-ANSYS, a super high-rise building structural analysis model was established, inputted the fitted long-period seismic response spectrum and the design response spectrum of Shanghai anti-seismic standards, by comparing the results of structural seismic responeses under the two kinds of response spectrum, the long-period seismic response of super high-rise building was investigated, and some valuable conclusions were obtained for reference.

As a new kind of concrete construction technology, fair-faced concrete is still not mature and applied widely in China by present. But it was successfully used in China Qingdao Zhuoting plaza project. Its No.1 and No.2 dwelling houses are high-rise buildings with thirty-two stories and their external walls were constructed with fair-faced concrete. As it is the highest fair-faced concrete project in China with 99.95m in height and 370 days construction period through four seasons in a year, the project meets a lot of problems and challenges. So some innovative construction technologies were studied and used which make the project smoothly and successfully completed and get many significant economic, social and environmental benefits.

Wind Induced Vibration

The importance of wind induced vibration is a key factor in the analysis, design and construction of high-rise building structures. Owing to scarce land resources, urbanization and ever-growing demand for accommodation is leading developers into sloping (hilly) grounds which in turn requires researches on the structural equilibrium of these structures. This study draws to mind the requirements of a fast-growing city of the Federal Capital Territory, FCT, Abuja considering her vast undulating planes and plateaus, high altitudes and windspeeds (50 m/s). Here therein, lies a comparative study of different types of building configurations and responses for sloping grounds using approaches form seismic analyses as a background to achieving set objectives. The study therefore, attempts the application of a commonly used method (Static Wind Analysis, SWA) for analysis of wind loads on structures and also understudying the outcomes of applying the same loads using dynamic method (Response Spectrum Analysis, RSA). STAAD Pro V8i software was used to synthesize both analyses using the ASCE 705 code (wind speed-up over Hills) on 40 models for each analysis method for a 3x5 planar building configurations (G+6, G+8, G+12 and G+18) on grounds (0°, 6°, 14°, 18°, and 27°). The findings confirmed the complexities of sloping ground buildings with a greater chance of vibration and sway for SWA than in RSA. It was concluded, that the Stepback-setback (STPB-SETB) frames were better configured to combat wind loads on sloping grounds for both analyses. Recommendations includes, prioritizing the construction industry, collaboration with international bodies on High-rise development, developing a data base and wind testing facilities.

It is a big challenge that the tall buildings must withstand the various forces acting from different directions and aspects such as seismic and wind forces while designing the tall structures it is mandatory to deeply understand the seismic and wind behaviour of multi-storeyed buildings. In this study we are concerned to determine and analyse the seismic and wind behaviour of high-rise buildings some of which were regular and other had irregularities in them in their plan and elevations. Three G+30 storied buildings were considered which were situated in seismic Zone-V and analysis were carried out using response spectrum method as per IS 1893- 2016 on ETABS software. Each building is subjected to wind load at different terrain categories to examine its effects at different slopes as per IS 875 Part 3 2015.Various parameters like Auto lateral load, maximum storey displacement, maximum storey drift, overturning moment, storey shear and time period were considered in this study. It is concluded that vertical irregular building in terrain category-4 with ground slope less than 3 degree’s provides greater resistance against both seismic and wind loading among all buildings.
