摘要
提出了一种设计与施工一体化时变分析模型,即把结构施工过程与结构成型后的荷载效应分析融在一个时变结构有限元分析模型中,使其自动考虑施工过程的预应力张拉、加载顺序及其他因素的影响;结合北京某建筑玻璃采光天顶的张弦梁-单层索网杂交支承结构体系,基于结构设计与施工一体化时变分析模型,对屋面找平及考虑预应力张拉顺序的结构荷载效应进行了研究。结果表明:采用该模型进行屋面的找平分析、结构的荷载效应分析,可使结构设计更加合理、可靠。
A new kind of design-construction integrated time-varying analysis model was proposed,in which construction simulation and load effect analysis could be carried out.The integrated model could automatically consider the effects of tensioning schemes,loading sequences and other factors.Analyses of the form-finding and structural load effects were made to a glass roof,which was built on one building in Beijing and contained a supporting structure system hybridized by bidirectional beam string structure and monolayer cable net.Results show that using the integrated model to do form finding and structural load effect analysis makes the structure design more reasonable and reliable.
