摘要
The static test of two single light wood trusses and two girder trusses were carried out to explore theperformance enhancement effect of girder trusses and the influence of different connection types on the mechanicalbehavior, which was studied through the comparison of the test results of four trusses. It is found that the girder trussescan show better load-carrying capacity and anti-deforming ability compared with which simply increases the cross-sectionsize of the members. Because of the advantage of the connection materials and the non-fastening connection mechanism,the wood pin-connected truss has more ultimate bearing capacity which is 2.6 times of single truss, and better deformationresistance which is only 66.2% of the nailed one’s creep value.
