为研究基于压力路径法的钢筋混凝土梁的受力性能，设计了剪跨比分别为4. 0、3. 0、2. 5、2. 0、1. 5、1. 0 的 6 组试件，每组 2 根梁，通过单调加载试验，探讨了剪跨比对压力路径法配筋梁受力性能的影响规律，并将结果与我国混凝土结构设计规范配筋梁进行了对比，分析了破坏过程及破坏模式、极限荷载、荷载 － 挠度变化、荷载 － 应变变化等力学性能。结果表明: 试验梁中沿压力路径传递的应力是影响构件抗剪承载力的主要因素，在所采用的6 种剪跨比下，压力路径法配筋梁能保证梁的抗剪承载力，其极限荷载与规范法配筋梁的相差并不明显，但基于压力路径法配筋能够减少箍筋用量，且剪跨比越小，所节约的箍筋量越大。试验结果验证了基于压力路径法配筋的合理性及有效性。

In order to study the mechanical behavior of reinforced concrete beams based on compressive force path method，six groups of specimens with shear-to-span ratios of 4. 0，3. 0，2. 5，2. 0，1. 5 and 1. 0，with two beams in each group，were designed． Through the monotonic loading test，the influence of different shear-to-span ratios on the mechanical behavior of reinforced concrete beams based on compressive force path method was investigated． By comparing the results with those of reinforced concrete beams under the Chinese code for design of concrete struc-tures，the mechanical properties such as failure process and failure mode，ultimate load，load-deflection curves and load-strain curves were analyzed． The results show that the stress transmitted along the compressive force path is the main factor affecting the shear capacity of the test beams． Under the six different shear-to-span ratios in the test，the shear capacity of the beam reinforced by the compressive force path method can be well guaranteed，and the ul-timate loads are not significantly different from those of the beams designed by the current code in China，but the amount of shear stirrup according to the compressive force path method can be desirably reduced． In addition，more stirrups can be saved with smaller shear-to-span ratio． The effectiveness and rationality of the compressive force path method was finally verified by experiments．
