Soft storey failure
Web6 Jan 2024 · When the infills are constructed discontinuously along the height of the structures, a soft storey mechanism can be excited, which is a brittle failure mode and can result in the catastrophic collapse of frame structures. Figure 1 shows a typical soft storey failure of a MIRCF in China’s Wenchuan earthquake. Therefore, these effects that the ... WebFig. 5: First Soft Storey Failure Mechanism in Multi-Storey Masonry Building 7. Connections of Crossing Walls In a seismic-resistant masonry building, crossing walls have to be interlocked properly to improve out-of-plane strength. The problem of unconnected intersecting walls is very common. Due to bad connection detail of the intersections ...
