摘要:
按照清代工部《工程做法则例》的要求,以1:2.65的比例制作了4榀宫殿式木结构框架模型,并进行低周水平反复荷载试验。对木框架的破坏形式、节点拔榫量、滞回曲线、变形能力进行了分析。试验结果表明:脱榫是木框架模型破坏的主要形式,梁、柱构件变形较小,未出现破损;在水平反复荷载作用下,节点拔榫量随着控制位移的增大而不断增加,榫头正截面与卯口正截面挤压变形较小;木框架模型弯矩-转角滞回曲线形状总体呈倒“Z”字型,榫卯之间在受力过程中发生较大的滑移,节点表现出半刚性的特点。木框架最大侧移为120mm,具有很好的变形能力;各框架节点刚度随着转角的增大而逐渐减小。
Abstract:
Four palatial timber frame models made according to the requirements of the Gongcheng Zuofa of Qing Dynasty and with the proportion of 1:2.65 were tested by low-cyclic loading. The behaviors of timber frame models, such as the failure forms, pulling out length of the tenons, hysteretic curves, deformation and degeneration of rigidity,were analyzed. The test results indicate that the separation between mortises and tenons is the main destructive type of the timber models,and the deformation of the beams and columns are smaller. Under the horizontal low-cyclic loading, the pulling out length of the tenons increases with the increase of displacement of the frames, and the squeeze deformation between the cross section of the tenons and the cross section of the mortise is small. The shape of moment-rotation hysteretic curves of every mortise-tenon joints presents a reciprocal shape of "Z", and the bigger slip displacement occurs between mortises and tenons in force process. The maximum horizontal displacement of the timber frames is 120 mm, and exhibits a good deformation behavior. The rigidity of the mortise-tenon joints reduces with increase of the rotation.
