摘要
结合工程实例,以某混凝土连续梁变更预应力筋张拉方式为研究内容,采用BSAS软件建立了全桥有限元模型,分析了拟变更方案对结构受力状态的影响,并确定了最终的变更方案。
Combining with the engineering example, the paper regards the alteration of prestress tensioning method of some concrete continuous beam as the research object, adopts BSAS software to establish the whole-bridge finite element model, analyzes the alteration scheme’ s influence on the structural stress status, and identifies the final alteration scheme.
