通过某机房改造工程,介绍了体外预应力加固简支梁在工程中的应用。采用直接计算承载力增量的计算方法,对体外预应力钢绞线所提供承载力增量进行计算分析。结果表明,体外预应力加固简支梁可以有效地提高结构的承载能力,同时也提高了结构的正常使用极限状态。采用直接计算承载力增量的方法比传统计算方法简便,计算公式直观,结果可信。
Through a computer room renovation project, introduced in vitro prestressed reinforcement simply supported beams in engineering applications. The calculation method of incremental calculation of bearing capacity is adopted to calculate and analyze the increment of bearing capacity of externally prestressed steel strand. The results show that the prestressed reinforcement simply supported beam can effectively improve the carrying capacity of the structure, and also improve the normal operating limit state of the structure. Adopting the method of calculating the increment of bearing capacity directly is simpler than the traditional calculation method, the calculation formula is intuitive and the result is credible.
