连体结构弹塑性时程分析的初始内力条件
Initial Inner-force Conditions in the Elastic-plastic Time-history Analysis of Con-jointed Structure
【摘要】 以某高层连体结构为工程背景,分析了对连体结构弹塑性时程分析结果影响显著的两个初始条件及其对结构初始内力的影响,通过背景工程弹塑性时程分析结果对比,证实了此类结构以施工过程分析结果作为结构弹塑性时程分析初始条件的必要性,最后针对连体结构提出了减少结构附加内力的措施.
【Abstract】 Based on a high-rise con-jointed building structure,we analysed some initial inner-force conditions which have significant influence on the elastic-plastic time-history analysis of con-jointed structure and the significance of their influence on the initial inner-force of a structure. The study then verified the necessity,in this kind of structure,to put analysis results of construction progress as initial condition of elastic-plastic time-history analysis through the comparison of analytical results of background project. Finally we put forward some practical measures to minimize additional inner force of large-span con-jointed structure.
【Key words】 con-jointed structure; initial conditions; additional inner-force;
