Abstract Considering the glulam beam-column connection form and the number of bolts, monotonic loading test and
finite element analysis was carried out on 9 connection specimens in 3 groups to study the rotational performance
and failure mode of the connection. The test results revealed that compared with U-shaped connectors, T-shaped
connectors can effectively improve the ductility of connections, and the increase in the number of bolts can
reduce the initial stiffness and ductility of connections. By theoretical analysis, formulas for calculating the initial
stiffness and ultimate moment of connections were deduced. Subsequently, the moment-rotation theoretical model of connections was established based… More >
