结合《建筑抗震设计规范(GB 50011-2001)》的相关规定,以汶川地震中映秀镇漩口中学食堂为例,采用常用的简化力学模型进行设计计算并与震害现象进行对比。得出RC框架结构中虽然设计计算考虑楼板对梁的刚度贡献,并由此梁端弯矩设计值进行梁端矩形截面配筋设计。但是由于没考虑板筋对梁端承载力的贡献,即使柱端增大了弯矩设计值,也在低烈度设防区形成“强梁弱柱”的结构。 Combining with the relevant provisions of Code for Design of Seismic Design of Buildings (GB 50011-2001), taking the simplified model of cantilever as an example in the dining hall of Xuankou Middle School in Yingxiu, Wenchuan Earthquake, the calculation is compared with that of seismic damage. It is concluded that although the RC frame design considers the contribution of the slab to the stiffness of the beam, and the design value of the bending moment of the beam end is used to design the reinforcement of the rectangular section of the beam end. However, due to the lack of consideration of the contribution of slab to the bearing capacity of the beam, even if the column end increases the design value of the bending moment, the structure of strong beam and weak column is also formed in the zone with low intensity.
