摘要

采用一种创新的混合混凝土和钢单元进行了试验测试，以确定一种更精确的方法来确定预应力混凝土梁的弯矩重分配系数。根据试验结果，提出了确定有粘结和无粘结预应力梁弯矩重分配系数的公式。

Differences in moment redistribution in concrete beams prestressed with bonded and unbonded tendons

Experimental tests using an innovative hybrid concrete and steel element were conducted to define a more precise method for determining the coefficient of moment redistribution in prestressed concrete beams. Based on the test results, formulas are proposed to determine moment redistribution coefficients for beams prestressed with bonded and unbonded tendons.
