In this paper,based on experiments and research, the behavior, the failure modes and the mechanisms of simply supported R.C. deep beams with web opening under concentrated loading on the top are discussed. Assuming both reinforcement and concrete as rigid plastic materials and using the failure criterion of concrete in biaxial compression, the plastic solution for shear strength of the failure section and the formulas for predicting the shear strength of R.C.deep beams with web openings in regards to different...

In this paper,based on experiments and research, the behavior, the failure modes and the mechanisms of simply supported R.C. deep beams with web opening under concentrated loading on the top are discussed. Assuming both reinforcement and concrete as rigid plastic materials and using the failure criterion of concrete in biaxial compression, the plastic solution for shear strength of the failure section and the formulas for predicting the shear strength of R.C.deep beams with web openings in regards to different failure mechanisms have been obtained. Finally, the method for limit analysis of shear strength of such deep beams is suggested,and the calculated results show a good agreement with the test results a-vailable at home and abroad.

本文在试验研究的基础上分析了钢筋砼简支开洞深梁在顶部集中荷载作用下的工作性能和破坏形态,给出了相应的破坏机构。假定钢筋和砼均为刚塑性材料,引用砼双向受压的破坏条件求出了剪切破坏面受剪承戴力的塑性解,并进而求出各种破坏机构对应的受剪承载力公式,提出了按塑性极限分析计算开洞深梁受剪承载力的方法,计算结果怀国内外试验资料符合均较好。

The concrete beams with web openings are classified according to their force feature through the analysis of experimental results of deep beams with web openings,short beams with web openings and shallow beams with web openings.The failure modes,effect factors and transmitting force model are elaborated separately.

The experimental research on shear properties of reinforced concrete continuous short beams with web openings under concentrated loads was made. These 32 beams included 20 simply supported short beams and 9 twospan continuous short beams with web openings as well as 2 simply supported deep beams and 1 two-span continuous deep beam with web openings. This type of design of beams was made in order to study the continuity...

The experimental research on shear properties of reinforced concrete continuous short beams with web openings under concentrated loads was made. These 32 beams included 20 simply supported short beams and 9 twospan continuous short beams with web openings as well as 2 simply supported deep beams and 1 two-span continuous deep beam with web openings. This type of design of beams was made in order to study the continuity of the deep and short beams with web openings. The results of the experiments showed that the failure modes of these short beams were consisted of shear failure and bending-shear failure and that there was a transition of the surface of shear failure from diagonal compression to shear-compression failure along with the increasing of depth-span ratio and shear span ratio. The depth-span ratio, shear span ratio, the size and the position of opening and the form and amount of reinforcement were main factors which influenced the expanding of cracks of short beams with web openings, the failure modes, shear capacity and the redistribution of support reactions.

本文对钢筋混凝土开洞短梁在集中力作用下的受剪性能进行了试验研究,32根试件中包括20根简支开洞短梁和9根两跨连续开洞短梁,另外还有2根简支开洞深梁和1根两跨连续开洞深梁,是为了满足开洞深、短梁研究的连续性。试验结果表明:其破坏形态主要有洞口上下剪切破坏型和弯剪破坏联合型两种,随跨高比、剪跨比的增大,剪切破坏面由斜压破坏向剪压破坏过渡;跨高比、剪跨比、洞口大小和位置、配筋形式及数量是影响开洞短梁的裂缝发展、破坏形态、抗剪承载力、支座反力重分布的主要因素。
