This paper highlights several issues of the procedures nowadays adopted for the recovery of
cross-sections stress distribution within tapered thin-walled I beams. In particular …

Non-prismatic beams are widely employed in strategic structures like bridges and sport
arenas, requiring accurate analyses for a reliable and effective design. Unfortunately …

In this paper, the visco-plastic behavior of solids is formulated based on the Hellinger–
Reissner variational principle. The latter provides an optimal basis to obtain an increased …

Displacement-based formulations for composite structures are directly linked to the
functional called the Principle of Virtual Displacements and present the minimum number of …

A novel strain-displacement variational formulation for the flexural behaviour of laminated
composite beams is presented, which accurately predicts three-dimensional stresses, yet is …

This paper illustrates an innovative approach to obtain an analytical model for elastic,
multilayer, anisotropic, and moderately thick plates. The goals of the proposed approach are …

The cable-stayed suspension bridge is one type of bridge that has been increasingly
applied to bridge engineering, especially in cross-sea projects. However, the complex …

An efficient, finite elements (FE) based method of cross-sectional analysis of a longitudinally
homogeneous beam, with an arbitrary cross section and material model assumed, submitted …

分析了现有的钢板桩计算理论, 计算了钢板桩围堰的土压力, 静水压力, 流水压力,
波浪力与支撑力; 分析了钢板桩围堰的施工工序, 将钢板桩视为非线性弹性地基梁 …

Aiming at the problem of the specified stress condition in a partial region of the structure, the
Hellinger–Reissner (H–R) variational principle is studied to provide a theoretical basis for …
