The design of intersecting nodes in high-rise oblique mesh structures is a critical issue. existing research on the meshes mainly focuses plane and monotonic axial compression loads. cannot consider contribution node’s out-of-plane angle floor beam to stiffness actual structures. In this paper, numerical analysis using ABAQUS was conducted investigate mechanical performance space (OMSIN) under ...

Abstract Concrete-filled steel tube (CFST) columns are widely used in civil engineering because of their excellent bearing capacity; however, the reinforcement CFST lacks effective measures. To strengthen quickly and effectively, two methods, namely, winding FRP (fiber reinforced polymer) or strips, were explored this work. Two unconfined columns, eight FRP-strengthened four welded strip-streng...

The double-skin profiled composite wall (DSPCW) system, filled with concrete material, is favorable in modern structures due to its high strength and ductility. Openings may be required within this for various reasons, similar a conventional bearing wall, which can lead reduction capacity. Therefore, avoid changes the geometry, materials, thickness of DSPCW new internally stiffening concept has...

Reduction in self-weight and achievement of full fire resistance requirements are some the important considerations design high-rise structures. Lightweight concrete filled steel tube (CFST) column provides an alternative method to serve these purposes. Recent studies on lightweight CFST columns at ambient temperature have revealed that foamed can be a beneficial innovative material. Hence, thi...
