Abstract:
In this paper is investigated the analysis of stress and deformation fields of shape complex beams. The shape complex beams are made from load-bearing sheet (trapezoidal sheet) circumferentially connected with strips of sheet metal, these beams are a substitute for more complex and heavier beams. The numerical analysis with static load are performed for these beams. The effect of three different types of connections between load-bearing sheet and strips of sheet metal is investigated. The first type of connection is represented by the trapezoidal sheet perfectly welded to the strips of sheet m

Abstract:
The discrete clamp is used to replace the integral clamp in the traditional stretch forming process, and the stretch forming process of complex curved parts is studied. With the trapezoidal profile part and the double curved top part as the research objects, numerical simulation of the stretch forming process with the integral clamp and the discrete clamp is carried out respectively. The numerical simulation results show that: compared with the integral clamp, it is easier for the trapezoidal profile part to fit the die during stretch forming with the discrete clamp, and the distribution of st

Composite metal decking has become one of the prevalent forms of Fast Track Construction for multi-story steel buildings. The in-plane stiffness of composite metal decks however is of considerable importance as they typically act as a diaphragm in lateral-load- resisting systems and thus attract a large in-plane shear. The diaphragm action or the in-plane shear capacity of composite metal decks remained a concern for structural engineers and designers. The present work aims to investigate the in-plane shear behavior of fiber reinforced composite metal decks and compare it to that reinforced wi

To investigate the effect of flange length on the transversal distribution of the longitudinal strain, FEM simulations are conducted with different flange length for three blank shapes; trapezoid, convex and concave.
