Penggunaan Washer Khusus (Besar) Pada Sambungan Baja Cold-Formed

. Bolt Connection Design for cold-formed steel could not use friction mechanism (AISI 2001). On other side, bearing mechanism which is based on bolt diameter and plate thickness indicates inefficiency of bolt USAge because of the minimum size of cold-formed steel plate thickness then fracture happens on plate side. Therefore the improvement of connection strength is needed. The improvement of friction strength which is neglected before could be done by using special washer (large) to enlarge plane of friction of connection
