设计2榀单跨门式刚架并进行静力加载试验,施加的荷载为1.20恒载+1.40活载和1.20恒载+1.40活载+1.40×0.60风载两种组合。分析刚架处于两种荷载组合条件下典型位置的内力和位移,试验结果表明,刚架满足设计要求。运用ANSYS的Shell 181单元进行有限元模拟,模拟结果与试验结果吻合较好。在验证有限元模型的可靠性之后,对模型施加荷载+活载组合并逐渐增大直至破坏,分析刚架最终的破坏模式及机理。
Design 2 榀 single cross-portal rigid frame and static load test, the applied load of 1.20 dead load +1.40 live load and 1.20 dead load +1.40 live load + 1.40 × 0.60 wind load two combinations. The internal forces and displacements of the frame at the typical positions under the two load combinations are analyzed. The experimental results show that the frame meets the design requirements. The ANSYS Shell 181 element is used for the finite element simulation. The simulation results are in good agreement with the experimental results. After verifying the reliability of the finite element model, the load + live load combination was applied to the model and gradually increased until it was destroyed, and the ultimate failure mode and mechanism of the rigid frame were analyzed.
