| 摘 要： | 建立一个简单、实用的新模型预测正交钢筋混凝土板的开裂行为。新的模型能解释箍筋对开裂行为的影响,同时也考虑了影响钢筋混凝土构件开裂行为的主要参数,包括混凝土抗拉强度、配筋率、钢筋直径、间距。采用平衡和协调方程,对钢筋混凝土单元进行研究,以求出钢筋和混凝土的平均应力。对本文试验研究结果以及涉及不同结构单元、荷载条件的已有研究成果进行一系列验证比较可知。所提出的裂缝间距模型能够预测不同荷载阶段的裂缝宽度值。在所研究案例中,试验值与模型预测值吻合较好。

| Abstract: | A simple,practical,and new analytical model that is capable of predicting the crack spacing of orthogonally reinforced concrete plate elements is developed.The new model can account for the influence of the transverse reinforcement on the cracking behavior.The major parameters influencing the cracking behavior of reinforced concrete members,such as the tensile strength of concrete,reinforcement ratio,bar diameter and spacing in both longitudinal and transverse directions,are also considered.A reinforced con... |
