芦山“4·20”地震单层砖柱工业厂房的震害分析与研究
|
摘要
根据"4·20"芦山7.0级地震灾区单层砖柱工业厂房量大面广、类型齐全,但震害情况却轻于农居砖混结构的特点,对单层工业厂房的分类和宏观震害进行了介绍,其中包括轻型钢架单层工业厂房、单层混凝土柱工业厂房和单层砖柱工业厂房三种。随后根据地震现场科学考察的实测数据,对9度区双石镇和龙门乡的3个典型单层砖柱工业厂房进行了具体的分析,给出了其震害现象、破坏机理及若干影响因素,并为今后的进一步科学研究、恢复重建和生产应用提供了参考性的建议和对策。
The "4.20" Lushan Ms 7.0 earthquake field has plenty and various single-story factory buildings with brick columns.Their aseismic ability is better than that of the rural masonry buildings in the earthquake.According to this situation,this paper introduced the classification macro seismic disaster of single-story factory buildings,which include single-story light steel frame factory buildings,concrete factory buildings and brick column factory buildings.Then,with data from earthquake field investigation,3 typical single-story factory buildings with brick columns were analyzed,and their disaster phenomena,failure mechanism and several influence factors were studied.Finally,some suggestions and measures for further research and reconstruction,application of the buildings were proposed.
