Probabilistic seismic demand and fragility analysis of a novel mid-rise large-span cassette structure

Comparative study on overall and local static performance of steel open‐web girders

“…[1][2][3] Chen et al investigated in detail the comparison of concrete cassette structures with ordinary frame structures in terms of static, dynamic, and economic indicators through numerical simulation and shaking table tests. [4][5][6][7][8] The study shows that the cassette structure has the advantages of high lateral stiffness, good seismic performance, cost-effectiveness, high space utilization, and effective reduction of total floor height. However, in the simulation and test of the structures, the open-web girder is often replaced by the DRSB, which results in the fact that the actual stress, deformation, and failure characteristics of the open-web girder cannot be truly reflected.…”
