【摘要】 为得到力筋放张后斜梁的真实应力状态,进行了现场张拉应力测试。由于斜梁理论具有一定的局限性,故借助ANSYS软件对其进行建模得到应力精确值,并将三者的计算结果进行比较分析,借此对结构的安全性进行评价,以期为先张斜梁的张拉应力分析提供了有效的方法和途径。更多还原

【Abstract】 In order to acquire true stress behavior of skew beam after releasing steel wires,a tension stress test was done on the site.Considering the limitations of the skew beam theory,a finite element model is established by using ANSYS in this paper in order to get exact stress value.Calculation results from the above three approaches are compared and analyzed and structural security is accordingly appraised,which provides a valid method and approach for tension stress analysis of pretensioned skew beam.更多还原
