2种不同构造形式的钢-混组合桁架节点试验研究
Experimental study on steel-concrete composite joints with two kinds of fabrication
摘要
Abstract
Steel -concrete composite truss is a new structural form composed by steel braces and concrete chord. Two different kinds of composite joints model experiments were carried out, and the test methods and results were introduced in the article. The mechanical performance under the behaviors of loading process was described, then a comparative analysis of different joint's mechanical behavior, ultimate bearing capacity and failure mode was conducted. The experimental results show that failure modes include the cracking mode of concrete, plate yielding and bolt slipping. The different FEA results were compared to the test results which were simulated through ABAQUS software, which show the weak parts of different joints and how to effectively improve the bearing capacity. Test results can provide references and theoretical basis for the similar projects on the joint design.关键词
