单层单跨钢筋混凝土框架结构试设计对比分析

Comparative Analysis on Trial Design of Single-layer Single-span Reinforced Concrete Frame Structure

国家标准《室外给水排水和燃气热力工程抗震设计规范》(GB50032-2003)局部修订增加的一个重要内容是补充厂站建筑工程中单层钢筋混凝土框架房屋的抗震设计规定,其抗震等级和弹性层间位移角限值相对于《建筑抗震设计规范》(GB50011-2010)均有放松编制组选取大量模型,采用PKPM软件的SATWE有限元分析程序对单层单跨钢筋混凝土框架进行试设计,考察设计结果的变化、规律。通过试设计表明,按弹性层间位移角限值1/450设计框架时,设计结果合理可靠,与现行规范协调。

An important part of revising "Code for seismic design of outdoor water supply sewerage gas and heating engineering" GB50032-2003 is to supplement the seismic design of single-slab reinforced concrete frame buildings,and its seismic grade and the limit of elastic inter-story drift ratio is relaxed relative to the GB50011-2010.Standard preparation team selected a large number of models and conducted trial design by the SATWE finite element analysis software,researched the variation of the results.Through the trial design,the design results showed it is reasonable and reliable when the frame is designed according to the elastic interstory drift ratio limit of 1/450,and it is coordinated with the current codes for seismic design.
