Selection Of

Prevailing analysis and design of reinforced concrete (RC) structures is a critical stage in the construction industry to deliver the projects within the estimated construction time period and within the budget. The selection of suitable structural engineering software to perform the analysis and design tasks is not an easy matter of fact, especially with the existence of many specialized software in this domain such as Robot Structural Analysis, MIDAS Gen, SAP 2000, STAAD.PRO, Tekla Structural designer, S-Frame and many others. So a strong comparison between the existing software must be made before taking the final decision of selecting any software. The main goal of this paper is to present overall guidance for selection of the suitable software among the most common software used for the analysis and design of RC structures along with the supported design codes, analysis types and design modules incorporated in each software. The technical specifications, characteristics, application domains, incorporated structural design codes, limitation, technical popularity and capabilities of the existing most common used software were studied and compared. Based on the performed study, eleven software were selected and presented as a useful guideline for the structural engineers in the analysis and design of RC structures. In this paper, a complete guideline including the required technical information for structural engineers to choose the suitable software for analyzing and designing of the RC structures is presented.

The primary focus of this research is to analyze and design a multi-storey building (3D-dimensional reinforce concrete frame), the designing of building begins with making the plan of specific building which include the position of rooms, kitchen, toilet etc. the design should be such that it is up to mark of customer requirements and comport nowadays vastu shastra is also kept in mind while designing. The second step is to design the reinforced concrete part which includes designing of slabs, columns, beams, staircase and footing these designing’s were done manually and all the calculations were done according ACT code and the outcomes were compared using STAAD PRO. I design an office building which is made of reinforced concrete frames and the building has three floors with 12 offices on each floor which sum up to 36 offices and the maximum area of a floor is (21.9*40.9) m2. To complete the architectural design, I AutoCAD program and for analyzing and designing the structure of building I used software known as STAAD Pro v8iSSS.and after both the designing I got the results as the map of a building which is architectural and structural safe. For designing the structural plan and architectural design one requires high imagination power as well as theoretical knowledge and also keen knowledge of science of structural engineering and should know the recent design codes, laws and before designing he should have adequate experience and mind set to reach conclusion. STAAD PRO is a very user friendly software it is and easy to understand and operate. We can input the material properties, load value, dimensions and we can also draw the frame within the software and after taking all the data it analyze the whole structure and design the member with reinforced detail for concrete frame and all the designs are done under specified criteria. These criteria are implemented to keep careful balance between economy and safety.

The construction of a 5-stored parking building is planned to use a flat slab (with drop panels). Flat slab (with drop panel) is a type of two-way plate without beams that directly rests on the column. the flat slab can reduce the height of the structure and construction time. However, flat slabs require plates that are thicker than usual to overcome deflection and punching shears. In this final project, a 5-story reinforced concrete structure will be reviewed with a span of 8 x 8.3 m. Analysis and design was carried out with the help of the 2016 ETABS program to find the value of intersection between floors, shear moments and forces taking into account the consequences of dead load, super dead load, life, and earthquake (dynamic)

Abstract Ductility is a recommended characteristic by different RC structures design codes around the world, such as ABNT NBR 6118 [2], ACI 318 [1] and EUROCODE 2 [4]. Despite the recommendation of ductility, the codes only define this criterion in a qualitative way, without quantification about how ductile the structure is, and not being able to stablish a ductility level in the design phase. In this context, this paper proposes a new design model of reinforced concrete beams in bending considering the explicit definition of the input parameter named ductility factor, which quantifies the structure’s ability to withstand displacement before it breaks.

Educational approaches in structural engineering have focused on classical methods for solving problems with manual calculations through assignments, quizzes, and exams. The use of computational software to apply the learned knowledge has been ignored for decades. This paper describes an educational approach to tackle the lack of applicable practical exercises in the structural engineering class “CE 506-Prestressed Concrete” at a university in the western United States during the spring of 2017. The class was designed to provide students with the theoretical concepts of prestressed concrete and the ability to interpret applicable design codes. In their project, students continued to build this knowledge by designing a prestressed bridge superstructure according to a unique state design manual. Students prepared a literature review of their selected state in the U.S.A. and used commercial software to perform an analysis and design of their bridge. Additionally, students were asked to backcheck their design using theoretical methods through manual calculations. By the end of the class, students presented their projects in a head-to-head presentation format, to contrast the differences between their designs in a competitive style. This paper summarizes the class structure, the outcome of the design project, and recommendations for future applications of computer technology in structural engineering education.

Fibre Reinforced Polymer

Rehabilitation and strengthening of old structures using advanced materials is a contemporary research in the field of Structural Engineering. During past two decades, much research has been carried out on shear and flexural strengthening of reinforced concrete beams using different types of fibre reinforced polymers and adhesives. Strengthening of old structures is necessary to obtain an expected life span. Life span of Reinforced Concrete (RC) structures may be reduced due to many reasons, such as deterioration of concrete and development of surface cracks due to ingress of chemical agents, improper design and unexpected external lateral loads such as wind or seismic forces acting on a structure, which are also the reasons for failure of structural members. The superior properties of polymer composite materials like high corrosion resistance, high strength, high stiffness, excellent fatigue performance and good resistance to chemical attack etc., has motivated the researchers and practicing engineers to use the polymer composites in the field of rehabilitation of structures. This paper reviews fourteen articles on rehabilitation of reinforced concrete (RC) beams. The paper reviews the different properties of Glass Fibre Reinforced Polymer (GFRP) and Carbon Fibre Reinforced Polymer (CFRP) composites and adhesives, influence of dimensions of beams and loading rate causing failure. The paper proposes an enhanced retrofitting technique for flexural members and to develop a new mathematical model.

Abstract This paper present outside strengthening with precast substructures, is a relatively new retrofitting approach that has recently attracted the attention of researchers. Outside strengthening with precast substructure, in contrast to member-level strengthening technologies (e.g., FRP strengthening, enlarging member section areas, and replacing rebars), is a structure-system reinforcement method that integrates the substructure and the original structure, improves overall seismic performance, and changes the deformation mode of the entire structure. The seismic capability of the exterior strengthening with precast bolt-connected steel-plate reinforced concrete is critically evaluated in this paper (PBSPC) Case studies are used to demonstrate the working principles, numerical methodologies, and design approaches. The simulation results were similar with prior studies, demonstrating that the numerical model was effective. The use of building steel representations reduces construction time, increases efficiency, and lowers costs. The goal of this technology is to lower the seismic displacement demand of nonductile. Current RC structures have steel frames connecting to the building floors. These frameworks run parallel to the structure of the building. Ganjan Life City, a building in Erbil, Iraq, is being used as a case study. The ISC 2017 and ASCE 7-10 earthquake codes were used to evaluate the building’s seismic performance before and after the reinforcement. The analysis’ findings suggest that the recommended technique is correct.

Capacity Performance

Investigation of carrying capacity performance of reinforced concrete (RC) structures is very important for structural engineering. In this study, it is aimed to examine the nonlinear carrying capacity performance of an RC laboratory structure by using three dimensional (3D) modelling approach. For this purpose, Zonguldak Bulent Ecevit University Laboratory Structure is selected and it is modeled as three dimensional by utilizing IDECAD static software. After modelling all beams, columns and floors according to 2018 Turkish earthquake code, concrete classes are determined for all bearing elements and specified concrete classes are defined for all elements of 3D model. Then, structure is analyzed for empty situation (Case 1) and structural performance of building is analyzed to this situation. In the past, a flat of this RC structure has been exposed to strong machine loads. For this reason, a machine which is fixed on the floor is placed in the 3D model and RC structure is analyzed considering nonstructural machine element loads (Case 2). According to analysis results, Case 1 is compared with Case 2 and it is clearly seen that nonstructural machine loads effect nonlinear carrying capacity performance of RC buildings.

Analysis and design of beam is still an important part in Structural Engineering practice. As a major component in structure, it demands due attention and accuracy. At the same time engineers need to achieve economy in time and cost in the design of beams. To assist designers moment coefficients are developed for continuous beams in this work. Existing ACI moment coefficients are applicable only under certain conditions and have some limitations. This study is an attempt to develop moment coefficients for beams which will be applicable beyond ACI limitations. Comparison of developed coefficients with corresponding ACI coefficients has been done and a satisfactory agreement is found. However, ACI coefficients are found to be conservative. Additionally design tables are developed for selection of RC beam section and reinforcement when design bending moment and shear are available. SAP2000 has been used for analysis of beams during the study. Models are used to generate exact moment coefficients for beams of different span ratios and spans under uniform loading. The moment coefficients and design tables generated in this work will be useful for practicing engineers for quick design. KEY WORDS: Moment Coefficient; Shear; Continuous Beam; Uniform Loading.
