摘要
基于长短期荷载试验 ,对混凝土板和钢梁均施加预应力的新型预应力组合梁的破坏形态、预应力损失、预应力筋的极限应力、抗弯承载力、长短期变形等力学性能进行了较为深入的研究 ,并系统地提出了有关设计建议 .
Based on experiments under short-term and long-term loads,studies on failure patterns,prestressing loss,ultimate stress of tendons,bending capacity,short-term and long-term deflections of new-type prestressed steel-concrete composite beams with prestressed concrete slabs and prestressed steel beams are studied in detail,and the corresponding design suggestions are systematically put forward.
