Usually, the connection between the frame structure and the frame column can only form an effective structural system to resist horizontal loads (wind loads and earthquake loads) if it achieves the connection performance of rigid connection. Therefore, the development of an effective lateral force resistance system for glulam beams and steel columns has become the focus of promoting glulam structures. Utility Model Content
