考虑木柱协同工作的古建筑木构架受力性能试验研究
Experimental study on the mechanical behavior of traditional timber frameworks considering the collaborative work of wooden columns
摘要
Abstract
The wooden column is the main load-bearing and lateral resistance unit of traditional timber struc-tures,and its mechanical behavior is the basis of studying the overall performance of traditional timber struc-tures.In this paper,a wooden frame in the Daxiong Hall of Fengguo Temple is taken as the prototype,and the low cycle repeated load tests of a single column and a frame with E-fang were conducted.The deformation modes and mechanical properties of the two experimental models are compared.It is found that both the wooden column and the frame sway under repeated loads,but the uplifting of the column foot of the frame is significantly less than that of the single column due to the transverse tie effect of the mortise-tenon joints,indi-cating that the transverse restraint of E-Fang enhances the stability of the wooden column.The hysteretic curve of the single column is S-shaped,while that of the frame tends to be a parallelogram.The synergistic working mechanism between the wooden columns significantly improves the lateral bearing capacity of the frame.The positive and negative bearing capacities of the frame are 136.43%and 115.53%higher than those of the un-constrained double columns,respectively.It shows that the tie effect and cooperative work of the transverse members and mortise-tenon joints have a positive effect on the lateral resistance of the frame,making it form a stable plane force system.The research results can provide an experimental basis for the analysis of the overall working mechanism and mechanical performance of traditional timber structures.关键词
