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。
According to “4.20 ” Lushan 7.0 earthquake disaster area brick single-storey industrial plant large volume, wide range, but the damage is lighter than the characteristics of rural residential brick structure, the classification of single-layer industrial plant and Macro-seismic damage were introduced, including light steel frame single-storey industrial plant, single-story concrete column industrial plant and single-brick industrial plant three. Then based on the field survey data of the earthquake, three typical single-storeyed brick factory buildings in Shicang and Longmen townships of 9 degree are analyzed concretely, and the seismic damage phenomenon, failure mechanism and some influencing factors are given. And provide reference suggestions and countermeasures for further scientific research, restoration and reconstruction and production and application in the future.
