THE EXPERIMENTAL RESEARCH ON THE STIFFNESS OF PRESTRESSED CONCRETE BEAMS UNDER LONG-TERM VARIABLE LOADS
-
摘要: 通过对预应力混凝土梁在可变荷载作用下为期两年的长期试验, 对其刚度、挠度及截面应变进行实测, 依据测试结果, 对现行规范长期荷载作用下受弯构件刚度的计算公式进行了验证。Abstract: Through two year. s experiment on prestressed beams under variable loads, the stiffness, deflection and crosssection strain of prestressed concrete beams are measured. According to the test results, the calculating formula of national code on the stiffness of fluxural member is verified.
