摘　　要：新型厂房具有活荷载大、跨度大、层高高、层数多等特征。介绍了厂房结构方案比选、活荷载相关系数的取值、地震作用计算参数及活载的重力荷载代表值组合系数的取值。分析了产业园中“假厂房”的活荷载取值、底部楼层刚度偏小的对策、高大砌体填充墙的稳定性问题。提出了针对楼板易开裂部位的技术处理措施。New type of factory building has the characteristics of large live load,big span,high floor height and multi-ple floors.An introduction was made on the comparison of factory building structural schemes,the selection of live load correlation coefficient,seismic action calculation parameters and combination coefficient of gravity load repre-sentative value of live load.Analysis was made on the live load of"fake factory buildings"in industrial parks,the countermeasures for too low stiffness of the bottom floor,and on the stability problem of tall masonry infill walls.The author also put forward the technical treatment measures for the cracking prone areas of floor slabs.
