【摘要】 目前在江苏地区出现了大量以马鞍板为屋盖的单层工业厂房,但国内外对该类结构的抗震性能研究较少。本文对马鞍形板屋盖的单层工业厂房进行了多遇地震作用下的分析,探讨了地震波及各种结构参数的变化对结构自振特性和地震反应的影响,得出了厂房跨度越大,结构基本周期越大,结构所受的地震作用效应也越大等结论。采用有限元软件ANSYS对结构进行了数值分析,通过对理论研究结果与数值计算结果进行分析比较,并对此类结构的抗震设计提出了建议。更多还原

【Abstract】 At present,saddle plate is widely used in roofing board of bent frame structure of single-storey industrial building in Jiangsu,but,at home and abroad,the study on such structure is few.In this paper,the field of typical bents of the single-storey industrial building with saddle roof plate under frequently occurred earthquakes is mainly studied,and the influence of the dynamic characteristics and earthquake response of the structure through changing the seismic wave and other parameters is explored.And then,the conclusions are derived,such as the bigger the span of the building is,the basic cycles of the structure is the longer and the earthquake response that the structure receives is bigger,and so on.The structural numerical analysis is carried out with the finite element software(ANSYS),and the results are compared with the theoretical results.Based on these,some advices on aseismic design of industrial building with saddle roof plate are given.更多还原
