【摘要】 介绍了一种新的异型钢板粘钢加固负弯矩区抗弯不足的作法,并对其与规范中作法进行了有限元分析对比,结果表明这种作法可以有效提高被加固梁的承载力,使挠度明显降低,并且有效地抑制了裂缝在构件中的开展,计算证明此方法有效且可靠。更多还原

【Abstract】 The paper introduced a new method of strengthening concrete beam-column joint with externally bonded steel plate.Finite element analysis is done,and the result shows that the method can effectively improve the bearing capacity and reduce the deformation for the beam,and it can restrain the crack development in the structural member,the analysis result shows this method is reasonable and reliable.更多还原
