SUITABILITY OF COLLAPSE MECHANISM ANALYSIS FOR A SOFT-STORIED BUILDING

So for an earthquake resistant building should have good seismic configuration with no architectural choice in the form of building otherwise it will introduces complexities in the building behavior. In the same way building must possesses minimum lateral stiffness and strength in each of its plan direction so that no discomfort to the occupants with little damage during earthquakes. Building should also have good overall ductility to accommodate the imposed lateral deformation between the base and roof of the building and along with the desired mechanism of behavior at ultimate stage otherwise building will behave poorly. These four virtues are achieved by inputs provided at all stages of the development of the building as during planning, design, construction and maintenance
