Seismic Vulnerability Analysis of Masonry Structures Built with Disassembled Brick Wall Sections

Disassembling brick wall pieces into sections and constructing masonry buildings with disassembled (DBWSs) can reduce construction waste production at source help achieve carbon peak neutrality. A finite element model (FEM) for typical MSBD is established based on the calibrated analysis method to evaluate seismic performance of structures built (MSBD). Subsequently, ground acceleration selected as motion intensity index, maximum inter-story displacement angle chosen structural damage index. The 20 records are scaled by in 0.2 g steps form 120 structure-ground vibration samples incremental dynamic (IDA) vulnerability analysis. IDA results indicated that gradual increase acceleration, increases transits from elastic stage elastoplastic stage. Because characteristics different, order plasticity development will be different number needs considered assessment. calculation not collapse under 7 8 degree design-based earthquake probability moderate severe structure rare minimal, according curves. indicate has good earthquakes meets requirements “perfect subjected frequent earthquake, reparable design no earthquake.” statistics provide a reference evaluation damage.
