The test results indicated that: crack similitude of reinforced concrete simple beams is not equal to model scale λ under the working load; when the amount and surface shape of reinforcing bar are same, the similitude of crack width, crack amount and crac

试验结果表明：在使用荷载下，钢筋混凝土简支梁的裂缝相似率并不等于几何相似比λ；当钢筋根数及形式相同时，不同模型比尺下的钢筋混凝土简支梁的裂缝宽度、裂缝条数及裂缝间距的相似率，均约等于模型几何相似比的平方根√λ；当钢筋根数及形式不同时，裂缝条数及裂缝间距的相似率仍然约等于√λ，而裂缝宽度的相似率近似与√λ成正比，但应同时考虑钢筋根数与钢筋表面形状对裂缝宽度相似率的影响。
