基于JC法的新型载车台主梁结构可靠度分析

以结构可靠度理论为基础，运用应力一强度干涉模型，结合旋转式立体车库载车台结构的受力特点，建立该结构关键截面承载能力极限状态方程。利用一次二阶矩法并考虑随机参数服从各种分布时梁的强度可靠性设计，建立载车台主梁的可靠度指标与验算点（JC法）的迭代模型，通过数值分析得出结构的可靠度。所建立的新型载车台主梁结构可靠性模型对于立体车库结构的可靠性设计及提升立体车库开发水平，具有一定的指导意义。

A structural reliability analysis of the main girder of the new-type car-carrying platform using JC method

Based on the structural reliability theory and by using a stress-strength interference model,combined with the characteristics of car-carrying platform in rotary stereo-garage,a load-carrying capacity limit state equation is herein established for the structure's critical section.In the process,first order second-moment method is used,with consideration given to the reliability design for the beam's strength when the random parameters obey various distributions,to establish an iteration model for the reliab...
