装配预制梁抗弯承载力试验研究

EXPERIMENTAL STUDY ON FLEXURAL CAPACITY OF PREFABRICATION AND ASSEMBLY BEAM

摘要: 为研究装配预制梁抗弯承载能力和变形性能,制作3根装配预制梁及1根对比梁进行混凝土梁的抗弯承载力试验研究,分析不同现浇企口连接的装配预制梁力学性能。研究表明,装配预制梁的破坏形态及变形能力满足设计要求,开裂荷载和极限荷载与整浇对比梁基本相同,同时根据试验数据找出了装配预制梁的预制段长度的适宜范围。

Abstract: In order to investigate the flexural capacity and deformation performance of prefabrication and assembly beam，three prefabrication and assembly beams and one cast-in-place RC beam were fabricated and the flexural capacity tests of RC beams were carried out． The mechanical properties of prefabrication and assembly beam with cast-in dapped-end connections were analyzed． The results showed that the failure mode and deformation of the prefabrication and assembly beam could meet the design requirements，cracking load and ultimate load were basically the same as the cast-in-place RC beam． Based on test data，the suitable range of the length of the precast section of the prefabrication and assembly beam was found out．
