Site-Specific Seismic Analysis of Buildings Supported by Lightly Reinforced Precast Concrete Walls

This paper aims to show the application of site-specific response spectra in analysis buildings that are supported by lightly reinforced precast concrete walls. Previous surveys on load-bearing walls multi-storey low-to-moderate seismic regions have found many existing with a connection reinforcement ratio less than wall ratio. When these subjected reversed cyclic loads, lateral is typically controlled rocking and ultimate performance governed ruptures dowels. uses moment–curvature analyses combination plastic hinge evaluate force–displacement capacity planar The building can then be assessed superimposing curve inelastic developed for site. proposed analytical approach illustrated through case study building. By comparing comparable limited ductile wall, it also that, although two exhibit similar force capacities, displacement significantly lower. finding highlights potential vulnerability some buildings.
