连续刚构桥偏载系数合理取值
Reasonable Value of Eccentric Load Coefficient of Continuous Rigid Frame Bridge
摘要
Abstract
For the proper values of eccentric load coefficient of continuous rigid frame bridge, relying on the eight loading test bridges, the eccentric load coefficient distribution regularity of the whole bridge is analyzed by comparing the finite element calculated values with experimental measured values.It is determined that width-span ratio and high-span ratio of continuous rigid frame bridge can be the main control factors of eccentric load coefficient.A calculation formula for eccentric load coefficient is put forward, and the finite element solutions are compared with the formula calculating values to verify that the accuracy of formula is within ±5%.关键词
