摘要
通过对预应力钢纤维混凝土梁和预应力混凝土梁的初裂载荷的比较,得出钢纤维对预应力混凝土梁的断裂性能有一定程度的提高。并通过ANSYS的模拟计算,两种梁在同级载荷的作用下,变形相似,数值则随载荷的增加相差明显。
Through analyzing comparatively cracking-lode of Steel Fiber Reinforced Prestressed Concrete Beam and Prestressed Reinforced Concrete Beam,there is conclusion that crack-capability of SFRPCB is an advancer in some extent than PCB.Using ANSYS simulating and calculating,both of beams are similar in deformation in the same load value,but discrepancy distinctly in absolute value become bigger and bigger with the value of load increasing.
