摘要：由于传统装配式混凝土梁运输和施工难度大，提出了一种新型钢节点装配式混凝土梁，并试制了1根现浇梁试件与3根装配式梁试件，通过抗弯静载试验，对比研究了新型钢节点对装配式梁试件力学性能及其破坏机制的影响。根据试验情况，采用ABAQUS有限元软件进行了试件破坏模拟，并与试验结果进行了对比分析。结果表明：装配式梁试件可达到现浇梁的承载力水平；新型钢节点的钢端板厚度对装配式梁试件的整体承载力影响较大，当钢端板尺寸在一定范围内时，装配式梁试件的承载能力优于现浇梁；新型钢节点对混凝土的破坏形式影响较大，其梁纯弯段裂缝不同于现浇梁的受弯竖向裂缝，表现为弯剪斜向裂缝；有限元模拟结果与试验结果相吻合，可用于装配式梁试件的后续研究。 Abstract: Due to the high difficulty in transportation and construction of traditional prefabricated concrete beams, a new type of assembled concrete beam with steel nodes was proposed. One cast-in-place beam specimen and three assembled beam specimens were fabricated on a trial basis to investigate the practicality of such assembled beams, the effect of new type steel nodes on the mechanical performance of concrete beams, and their influence on the damage of concrete through flexural static load tests. ABAQUS finite element simulation was used to compare and analyze the test results according to the test conditions. The results show that the new type of assembled beam can reach the level of load-bearing of cast-in-place beam. The thickness of the steel end plate in the node part has a greater impact on the overall load-bearing capacity of the beam, and the load-bearing capacity of this assembled concrete beam is better than that of cast-in-place beam when the size of the steel end plate reaches a certain level. New type of steel node has a greater impact on the destruction of concrete. The pure bending section crack of the beam is different from the bending vertical crack of the cast-in-place beam, which is the bending shear diagonal crack. The finite element simulation results coincide with the test results, which can be used for subsequent research on prefabricated beam specimens.

ABAQUS finite element simulation was used to compare and analyze the test results according to the test conditions. The results show that the new type of assembled beam can reach the level of load-bearing of cast-in-place beam. The thickness of the steel end plate in the node part has a greater impact on the overall load-bearing capacity of the beam, and the load-bearing capacity of this assembled concrete beam is better than that of cast-in-place beam when the size of the steel end plate reaches a certain level. New type of steel node has a greater impact on the destruction of concrete.
