摘要：
Based on the finite element software MSC.MARC, a refined finite element model was developed for simulating the collapse process of rural masonry structures. Based on numerical simulation, the seismic collapse analysis of typical self-built masonry structures with different seismic structural measures in rural area was carried out. The effects of the structural columns, the slab form and the supporting length of the precast slab on the structural seismic collapse resistance were studied. The results show that there are two main collapse modes, including the overall collapse caused by the failure of the masonry wall and the local collapse caused by the fall of precast slab. The structural column is a key measure to form an integral collapse mechanism and improve the collapse resistance of masonry structures. Precast slabs reduce the coordination of each piece of the wall, thus lowering the structural integrity and collapse resistance. When the support length of precast slabs is less than 100 mm, local collapse occurs. Masonry structure without any seismic structural measures may collapse locally under moderate earthquake, and the collapse resistance capacity is poor. © 2022, Editorial Department of Journal of Southeast University.
