摘要
以某试件为例,对钢梁高强螺栓拼接的耗能性能进行试验分析,并用有限元软件ANSYS对其进行模拟验证。结果表明:ANSYS能够很好地模拟试验试件。然后针对拼接区高强螺栓孔不同的开孔形式进行有限元模拟分析,结果表明:不同的开孔方式对拼接区的耗能性能有很大的影响,并给出了合理的开孔原则。
A specimen of steel beam’s high-strength bolted splice was carried out first to test its energy dissipation performance with finite element simulation followed by using ANSYS. Simulation results agreed well with the test results and showed that ANSYS can model the specimen well. Then finite element analysis of steel beam’s high-strength bolted splices with different opening methods of slotted hole was carried out.The analytic results showed that different opening methods had great effect on energy dissipation performance of splice and the feasible principle was given out.
