钢筋混凝土井字梁楼盖在某建筑中应用分析

Application Analysis of Reinforcement Concrete Grillage-shaped Beam in Construction

针对钢筋混凝土井字梁结构体系的受力特点,对其一般构造要求进行综合阐述。结合工程实例,对井字梁配筋量、边梁配筋量、边梁扭矩值和弹性最大挠度值进行分析研究。结果表明:边梁与井字梁间的刚度分配会对井字梁内力产生不可忽视的影响,导致井字梁的配筋量产生较大变化,边梁自身的扭矩也会产生较大变化,而边梁刚度的变化对自身的配筋量影响较小。同时,应将井字梁、边梁、柱等作为一个协同工作的空间杆系进行分析计算以反映结构的真实情况。

Due to the loaded particularity of reinforced concrete with grillage-shaped beam, commonly construetion was expounded generally. According to a example , reinforcement of grillage-shaped beam,reinforcement of boundary beam ,torque of boundary beam and elastic flexility limit were analyzed. The result demonstrated that stiffness distribution between boundary beam and grillage-shaped beam came into being influence to the internal force of grillage-shaped beam. The influence resulted in much change of reinforcement and torque of boundary beam. But the change of stiffness of boundary beam resulted in little change of itself reinforcement. At the same time, the grillage-shaped beam,boundary beam,column should be taken into account a cooperating space unit to reflect the true structure.
