摘要

建立了桁架类比法和圆盘模型法在钢筋混凝土受弯单元倾斜截面强度计算中的应用边界。确定了结构在剪力作用下的虚拟压缩单元(倾斜条)破坏区域和危险倾斜裂缝上的压缩区。采用单元感知到的最小极限力准则。基于塑性理论的变分方法，阐述了混凝土等级、相对剪切跨度和横向钢筋强度对单元强度的影响。得到了危险裂缝上斜带和受压区剪切破坏边界处的横向配筋系数值。

Improved calculation method of reinforced concrete elements strength on inclined sections

Application boundaries of the truss analogy and disk model methods to the strength calculation of reinforced concrete flexuralelements inclined sections are established. Areas of structures failure by virtual compressed element (inclined strip) andcompressed zone over dangerous inclined crack under the shear force are determined. The criterion of minimum limit force,which is perceived by the elements, is applied. Influence of concrete class, relative shear span and transverse reinforcementintensity on elements strength based on variational method in plasticity theory is specified. The data concerning the values ofthe transverse reinforcement coefficient at the boundaries of the failure from shear within the inclined strip and compressedzone over the dangerous crack are obtained.
