摘要： We propose two new types of timber-steel hybrid bridges which consists of the upper and lower stress-laminated decks connected by steel members with PC bars. One is the type utilizing trusses and the other is the type utilizing triangle hole perforated plates for the steel members. The proposed hybrid bridges have bending stiffness several tens of times larger than those of the one-deck stress-laminated deck bridge. The deck parts and steel member parts are so easily composed or decomposed that one can built the bridges or replace the decayed timber members in the field also at the time of disaster. We carry out the loading tests for the specimens of the bridges and confirm that they have practically sufficient stiffness. Lastly we extend the idea of these hybrid structures to the emergency bridge utilizing plywoods instead of the steel members for easy construction by human power.
