The shear resistance of steel frames infilled with CASIEL wall panels

摘要

In Europe, calcium silicate element (CASIEL) walls are increasingly employed as partitions and external claddings in buildings. When surrounded by frames, the interaction between the CASIEL infills and the frames has a significant influence on the load transmission paths of building structures. In order to safeguard the panels and the frames, as well as the finishes from damages, this behaviour needs to be understood and translated into design guidelines. This paper presents results of experiments conducted on 16 large-scale CASIEL-infilled steel frames loaded by in-plane shear. Parameters investigated include frame member size, rigidity of frame connections, frame-wall interface gaps, and bearing wedges at the frame top-corners, monotonic or cyclic loading. The basic behaviour is described, in terms of stiffness, strength and failure - modes
