中小学框架教学楼抗震设防标准提高对钢筋用量的影响分析

Seismic Fortification Criterion Improve Impact on the Steel Amount of Primary and Secondary Frame Structure Teaching Buildings

为了研究抗震设防标准提高后中小学框架结构教学楼钢筋用量的增加，通过研究规范中框架梁和框架柱的抗震措施，具体分析了影响中小学框架结构教学楼钢筋用量增加的因素。论文以太原市某中学框架结构教学楼为工程算例，利用PKPM结构设计软件，分别按标准设防和重点设防进行结构设计，并计算框架梁和框架枉钢筋的用量。对比得出中小学框架教学楼按照重点设防类别设计计算时，对框架梁和框架柱箍筋用量影响较大，箍筋用量增加101％，对框架梁和框架柱纵筋用量影响略小，纵筋用量增加了12．1％。为以后工程人员对中小学框架结构教学楼结构设计与工程造价控制提供参考。

To studied the standard flame beam and flame column in the a seismic measures, first studied the standard flame beam and flame columnin the seismic measures,conerete analysis the increased reason ofsteel consumption of flamework primary and secondary school buildings. In this paper, high school teaching building framework in Tai Yuan as the engineering study, Use PKPM structural design software. Design structure according to the standard fortification and focus fortification. And calculate steel amount of flame beam and flame column. Contrast to draw design and calculation according to the focus classification impact on the flame beam and flame column stirrup dosage is bigger, stirrup increased 101%;impact on the frame beam and flame column longitudinal reinforcement dosage slightly smaller, the amount increased 12.1%. For later engineering personnel to the flame structure of primary and secondary schools teaching building structure design and engineering cost control to provide the reference
