框架梁抗震箍筋弯钩节点构造设计及排布优化

The Structural Design and Arrangement Optimization of Frame Beam Seismic Stirrup Hook Node

20多年前,国家在地震经验不断积累、总结和理论实验研究水平不断提高的基础上,设计了混凝土梁、柱的抗震箍筋弯钩节点构造。随着社会的不断发展和进步给钢筋混凝土框架结构带来了诸多有利于框架梁箍筋弯钩受力工况的客观条件和因素。依据有利的客观条件和因素,并依照"安全、经济、耐久、适用"的准则,对框架梁箍筋弯钩的节点构造设计及排布进行优化,力求达到"保证效果、节省资源、方便施工"的目的。

The seismic stirrup hook node configurations of concrete beams and columns have been designed on the basis of experience in earthquake, the higher experimental and theoretical research. According to continuous development and progress of society, the good stress conditions for frame beam stirrup hook can be given. Based on favorable objective conditions and factors, and in accordance with the criteria of safe, economical, durable and suitable, the design and arrangement of frame beam stirrup hook node configurations have been optimized. The purposes of the paper are guaranteedresults, saving resources, facilitatiugthc construction.
