项目摘要
1. A method is proposed for the strength evaluation of plate panels under combined biaxial compression and lateral pressure. The validity of proposed method is demonstrated through systematically parametric studies for long rectangular plates and comparison with previous studies.2. A system is developed for reliability assessment of plate structures which are modelled as plane frame structures and subjected to combined biaxial compression and lateral pressure, based on ultimate collapse analysis.(1) Ultimate collapse is evaluated by using a linearized failure condition of the section under the combined effect of biaxial bending moment, torsional moment, shearing forces and axial force.(2) A matrix method combined with plastic node method is used to generate the safety margins of ultimate collapse modes.(3) Probabilistically dominant collapse modes are selected by applying the socalled branch-and-bound method.3. These methods are applied to a few plate structures with orthogonal stiffeners. The validity of proposed methods is demonstrated through numerical examples and comparison with other studies.
1.本文提出了一种计算双向受压和侧压复合作用下板的强度的方法。通过对长矩形板的系统参数研究,并与前人的研究结果进行比较,验证了本文方法的有效性.本文将板结构模拟为平面框架结构,在双向受压和侧压共同作用下,基于极限破坏分析,建立了板结构可靠度评估系统。(1)在双向弯矩、扭矩、剪力和轴力的联合作用下,采用截面的线性化破坏条件计算极限破坏。(2)采用矩阵法和塑性节点法相结合的方法计算了结构极限破坏模式的安全裕度。(3)概率主导崩溃模式的选择,应用所谓的分支定界方法.这些方法被应用到几个正交加筋板结构。通过数值算例和与其他研究的比较,证明了所提出的方法的有效性。
