Experimental study on mechanics performance of multi-bolt steel-glulam-steel joints
摘要
Abstract
The mechanics performance of multi-bolt steel-glulam-steel joints subjected to a load parallel to grain was investigated with 8 groups of 40 multi-bolt joints specimens. The failure mode and its mechanism were discussed. For multi-bolt steel-glulam-steel joints, results showed that the failure modes,bearing capacity , stiffness, and ductility were relevant to the rows of bolts, the number of bolts in a row and the way of bolts arranged. The bearing capacity of multi-bolt joints was nonlinear number of bolts. With the same number of bolts, the ductility of bolts arranged in multi-rows was better than that of one-row.关键词
