Ein Kehlbaken Dach mit gewählter geometrie wird in Hinblick auf seine Schnittgrößen zwischen Berechnung mittels RFEM 6 und der Handrechnung verglichen. Dabei werden insgesamt 3 最后一个未验算的系统。
在该示例中将有效长度和临界荷载系数与手动计算进行了比较,本教程将在 RFEM 6 中使用“结构稳定性”模块进行计算。 结构体系是在刚架结构上加两根铰接柱。 该柱子承受竖向集中荷载。
在本例中,不同时间浇筑的混凝土与相应钢筋之间界面的剪力按照 DIN EN 1992-1-1 确定。 下面将使用 RFEM 6 获得的结果与手算结果进行比较。
使用 RFEM 计算了湖相黏土上刚性方形地基[1]的沉降。 已对四分之一的基础进行建模。 基础两侧的宽度为 75.0 m。 施工阶段用于生成结果。
验证由合金 6061-T6 制成的不同截面的梁可以满足《2020 年铝合金设计手册》中规定的荷载要求。
这根 8 米长不同截面由合金 6061-T6 制成的铰接铰接梁并根据 2020 年铝合金结构设计手册计算绕弱轴屈曲的容许轴向抗压强度。
一个对称的浅结构结构,由八个相同的桁架构件组成,这些桁架嵌在铰支座中。 The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point when the snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at the given deflections.
