Effect of height to width ratio on seismic performance of X-shaped diagonally braced foam concrete composite wall panel

In this paper, based on the stress cloud simulation results of ABAQUS, the X-shaped diagonally braced foam concrete composite wall panels were designed and fabricated, and by selecting the optimal test scheme, the static test proposed to take the aspect ratio as the only variable was carried out to comparatively an-alyse the differences in seismic performance of the two types of composite wall panels with the change of aspect ratio, such as the damage characteristics and the force mechanism. The X-shaped diagonally braced foam concrete compo-site wall panels designed and fabricated in this paper were applied to the as-sembled monolithic reinforced concrete frame-diagonal braced structure, where the diagonal braces within the wall panels divided the wall panels and changed them from symmetrical parallelograms to stable force triangles, which im-proved the displacement and deformation capacity of the structure as well as its ability to absorb seismic energy. The combined force of the diagonal bracing, infill panels and frame makes the seismic defence shape of the structure no longer monolithic and improves the strength, stiffness, ductility, energy dissipa-tion capacity and stability of the structure; it improves the force performance.
