| 摘 要： | 提出了花岗岩石梁嵌入CFRP筋组合石梁技术,并进行了3根嵌入CFRP筋组合石梁和1根普通石梁的受弯性能试验研究.主要试验参数为嵌埋CFRP筋的直径和数量.试验分析了组合石梁的破坏形态、受弯承载力、变形性能、应变分布和CFRP筋的粘结滑移性能.试验结果表明:普通花岗岩石梁达到开裂弯矩时即发生脆性断裂,而通过在梁底受拉区嵌...

| Abstract: | A composite structural technique for improving the flexural performance of stone beams by mounting CFRP rods in the tensile region of stone beams was proposed.Three near-surface mounted(NSM) CFRP-stone composite beams and a conventional stone beam were tested to investigate their flexural behavior.The main test parameters were the amount and the diameter of NSM CFRP rods.The failure mode,flexural strength,deformation characteristics,strain distribution and bond-slip behavior between NSM CFRP rods and stone ... |
