【摘要】 本论文以W666型金属拱型波纹屋盖为研究对象,利用有限元计算程序SAP93对其进行动力模态及时程响应分析,研究波纹拱在18m、30m跨时该结构动力特性及其抗震性能。它可为波纹拱屋盖的抗风、抗震设计研究提供一定的理论基础,从而也为波纹拱的广泛应用提供合理的理论依据。更多还原

【Abstract】 This paper takes W666 arched corrugated metal roof as the object of study. Using finite element model program SAP93 to analysis the structure model by dynamic models and time history restart method, analysis the structure of dynamic properties and the earthquake reaction with 18m-span and 30m-span.This conclusion lay a foundation for anti-wind and anti-seismic design of ACMR. And also lay a rational theory for widely use of ACMR.更多还原
