钢筋骨架系统约束藏羌民居片石墙抗震性能
Restraints on Seismic Performance of Slab Stone Walls of Tibetan and Qiang Residential Buildings by Reinforcement Skeleton System
摘要
Abstract
In order to improve the seismic performance while maintaining the original style of the slab stone walls of Tibetan and Qiang residential buildings,the construction method of putting restraints on the slab stone walls of Tibetan and Qiang residential buildings by using a reinforcement skeleton system was proposed.Firstly,a typical wall of stone and wood structure in Lixian County was selected as the prototype,and a 1/2 scale ordinary slab stone wall W-1 and a wall W-2 with reinforcement skeleton system were designed.Secondly,comparative pseudo-static tests were carried out to study the failure forms,hysteretic properties,energy dissipation capacity,and deformation capacity of the two walls.Finally,the skeleton curves and hysteretic curves of the two walls were obtained by ABAQUS finite element numerical simulation and compared with the experimental results.The results show that the failure process of the wall under low cyclic load has an obvious stress stage,as well as crack initiation,expansion,and failure stages.Compared with those of the ordinary slab stone wall,the ultimate bearing capacity,energy dissipation performance,and failure displacement of the slab stone wall with reinforcement skeleton system are increased by 225%,183%,and 67%,and the cracking and damage degree of the wall are significantly reduced.The trend of skeleton curves obtained by numerical simulation and experiment is similar,with a S-shaped pattern.The shapes of hysteretic curves are different,but the hysteretic ring area of W-2 is larger than that of wall W-1.The ultimate loads of W-1 and W-2 obtained by numerical simulation are 21.62 kN and 78.04 kN,respectively,with a relative error of less than 20%compared with the ultimate load measured by the experiment.关键词
