摘要
介绍了混凝土徐变分析的原理及徐变结构分析程序PLECA编制的步骤 ,应用该程序对实际的简支梁桥和连续刚构桥进行了理论分析 ,并与实测结果进行了比较 ,验证了程序的可靠性。预测了结构的长期拱度变形 。
In this paper, the principle of creep analysis and the establishment steps of the PLECA, and the creep structure-analysis program were introduced. The reliability of this program to solve time-dependent analysis problems was tested and verified. A simply supported beam-bridge and a continuous rigid-framed bridge were analyzed, and the long-term deformations of these structures were estimated. In the end, some suggestions were given.
