This paper introduces the frame building made of glubam. Four beam-column portal frame specimens with steel bolted joints selected from the demonstration projects were subjected to lateral forces, to obtain monotonic and cyclic load deformation relationships and to evaluate the mechanical behavior of the glubam bolted joints. The test results show that the stress of each bolt in the bolt-group is uneven and split of glubam governs the joint failure. However the bolts with smaller stress could dissipate energy in the earthquake action. A significant difference was found between the experimental and analytical capacities based on GB 50005--2003 and ANSI/AF&PA NDS-2012 timber structures codes. However, it is recommended that the conservative design values based on current timber structure codes can be considered for design of glubam frames with bolted joints, in the absence of the specifications of glubam structures.
