Abstract

Abstract:

The mechanical properties and deformation characteristics of wooden column-beam structures are studied by using the wooden column-beam structures of a Xintai Warehouse as a prototype. The results show that the wooden column-beam joints have obvious semi-rigid connection characteristics, and the joint stiffness changes with the load. In addition, the upper and lower limits and the average value of the elastic modulus of the wood are determined relatively accurately by measuring the vertical displacement of the wooden beam and the lateral displacement of the middle of the wooden column, combined with the relevant calculation and analysis. The rotational stiffness of the column-beam joint and elastic modulus can be obtained by performing an on-site test on the wood structure to be tested using the proposed method. The results of this study have significance for the detection, identification and reinforcement design of historically protected buildings.

Key words: wooden structures, wooden column-beam joints, rotational stiffness, elastic modulus
