EFFECT OF NON-STRUCTURAL ELEMENTS ON THE OVERALL RESISTANCE OF A BUILDING

Abstract

Full-scale experimental checks and corresponding modeling efforts by way of researchers have revealed that, even though the structures designed in line with current seismic requirements maintain the MCE stage earthquake shaking, there may be a high degree of in-determinism in reaction and conservatism within the layout. This is obtrusive from the consequences of shake table assessments, wherein the structure is supposed to undergo intense damage as in line with the design recommendations, however simplest superficial damages occur. This indeterminism/redundancy is delivered using the contribution of “so-referred to as” non-structural partition walls and cladding to the structural response at the system level. This paper investigates this impact by designing and modeling CFS buildings at numerous proportions of non-structural wall panels. A simplified model incorporating a zero-length spring element is generated in OpenSees. The response of a building to lateral loading without and with facades was compared by performing a pushover analysis. The results determined that incorporating facades increases the stiffness of the building and prolongs its behavior in the linear range.
