Design and analysis of multistory building by using shearwall technology

Abstract

In early 20th century there is a revolutionary change in software development and programing that change also helped the field of civil and structural engineering to make the analysis made easy by developing easy user interface software’s. By the development of those sophisticated structural design software’s even the G+10 building can analyze and design within 48 hours of time. But if the same building, if we design by manual calculations it takes lot of time and the design report is like a book with thousands of pages. In this particular thesis the G+5 residential building is designed by adopting structural wall systems without any columns. The analysis and design of super structure done in Etabs software for dead load, live load, earthquake, wind load. The uncracked model is prepared and checked against the lateral deflections due to lateral forces and vertical deflections of elements due to self-weight and modal analysis is carried out. The modal analysis is carried based on tall story code and earth quake codes, the translation modes and rotation modes are observed Cleary and designed the structure against the torsional buckling also. The same structure is also analyzed and designed for serviceability criteria’s and strength criteria’s by adopting the modification factors to achieve the accurate values about the long term deflection in both vertical and horizontal direction. The auto construction sequence method adopted for the finding the long term creep deflection values of the flexure members. All the members are designed against all kind of static and dynamic loads. By adopting the geotechnical report of the soil, the foundation system is adopted based on the S.B.C value and the allowable settlement value and the shear stress and settlement and soil pressure values are checked. The design of the entire footing system along with soil structure interaction is done in SAFE software and the detailing and design of the elements are done by taking one element in each type in drafting software.
