Structural Analysis and Design of A Multistory Building and Studying the Effect of Masonry Infills

Abstract

As per the data released by the Central Statistics Office (CSO), the predictable growth in economic actions during the 21st century is 4.8% in construction and 2.8% in transportation. With mounting in globalization there is less land accessible for construction, thus the need of construction of off shore and on shore structures has amplified with time. But off shore and on shore structures are affected by wind, sea waves in addition to earthquake forces. Thus our project aims at design and construction of a structure that is along the coast line that is more prone to seismic actions. The consequence of masonry infill panel on the response of RC frame subjected to seismic action is widely documented and has been subject of several experimental investigations, while several attempts to model it analytically have been reported. Infill behaves like compression between column and beam and compression forces are transferred from one node to another. In this project the effect of masonry walls on high rise building is studied. Static analysis on high rise building with different arrangement is carried out. For the analysis G+15 R.C.C framed building covering G+10 and steel building for rest G+5 is modelled. Steel is more flexible material than concrete hence for high rise buildings steel is used for design. Concrete is quite good in compression, economical and easily available therefore must be used for designing structures. But when it comes to tall buildings , concrete provides major disadvantage that is poor tensile strength. Hence reliance on concrete cannot be laid in such situations. Therefore it is the steel that is to be used. Being light in weight, strong and more ductile it provides more liability against seismic hazards. So the main aim is to provide steel con concrete design that could be both economical and safe.
