Behaviour of R.C. Flat Slab G+10 Building Using Non Linear Static Analysis

Abstract

As we all are familiar with the fact that earthquake forces are random and dominant forces in nature, so in order to deal with such a hazardous force we use dynamic analysis and static analysis of building. Important parameter under seismic analysis includes ductility, stiffness, damping, mass, load carrying capacity, base shear, response spectrum, mass capacity curve and loading capacity curve. Indian Standard 1893-2016 is used to checkout seismic analysis of multi-storey building.
Earthquake engineering is a vast branch and varieties of method are used to carry out the calculation depending upon either external action of structure or behavior of structure/structural materials. The most common static and dynamic procedures include Linear Dynamic Analysis, Non-Linear Dynamic Analysis, Linear Static Analysis and Non-Linear Static Analysis. Pushover analysis is known as nonlinear static analysis. Generally in existing Structure we check the capacity or strength of building and nodal weak points in structure. For a particular type of earthquake seismic demand is analyzed using Pushover Analysis.
This analysis includes that buildings by non-linear load deformation in each members and element of multi-storey (G+10 in this project) subjected to monotonic horizontal loads representing inertia forced in a seismic until a ‘Target Displacement’ is maximum. Estimation of response characteristic like Force and Displacement capacities of structure is calculated and graph or a curve is plot. Due to increasing lateral loads, deformation takes place in individual members or element of multi-storey building until failure is observed in the respective element. Pushover Analysis also throws light on consequential effect on stability of structure. The overall design of seismic definition is carried out on E-tabs.
