Study On The Aseismic Performance Of Qiangzhai Blockhouse Structure In Taoping

Qiang architecture has remarkable regional and ethnic characteristics,which is in line with the living habits of local residents.Its building materials are mainly composed of the most primitive soil and stone,which can be obtained locally.In addition,the unique masonry technology makes the structure have good mechanical properties.The unique cultural atmosphere and exquisite architectural skills of the Qiang nationality,together with the Qiang architecture as the carrier of the intangible cultural heritage and material cultural heritage of the Qiang nationality,make it have a high research value.The Qiang inhabited areas in Western Sichuan are mainly located in the Longmenshan fault zone.In many earthquakes,many Qiang buildings have been damaged to varying degrees.At present,the research on Qiang architecture mainly focuses on the characteristics of history,culture and architectural style,but the research on the influence of the unique structural form of Qiang architecture on the seismic performance is less.The purpose of this paper is to study the aseismic performance of Taoping qiangzhai blockhouse structure.The finite element method is used to study the aseismic performance of Taoping qiangzhai structure system under the low cycle reciprocating load and seismic wave.The main research results are as follows:(1)Combined with the existing literature test,a separate finite element model of stone masonry wall is established.The numerical simulation results are in good agreement with the test results of the existing literature.(2)The control variable method is used to analyze the influencing factors of the stress performance of the blockhouse wall under the action of the low cycle reciprocating load.The influence rules of the three key factors of the wall score,the angle between the fish ridge line and the stone crossing the river on the performance indexes such as the bearing capacity and rigidity of the blockhouse wall are obtained,and the optimal range of the score and the angle between the fish ridge line are obtained Around.(3)Based on the law of influence factor analysis,the finite element model of the whole blockhouse structure is established by selecting the typical parameter value.The seismic performance of different blockhouse structures under the action of frequent earthquake and rare earthquake is compared and analyzed,and the influence of three influence factors on the seismic performance of blockhouse structure under the action of seismic wave is obtained.(4)According to the influence factors of three kinds of blockhouse structures,combined with the influence factors of blockhouse structure.In terms of force performance and construction difficulty,the optimization scheme of structural parameters of blockhouse is put forward for reference of practical engineering.
