“…While a few studies have used detailed models with solid elements to analyze the structural response of composite slabs in analyses of column loss at ambient room temperatures (e.g., Sadek et al, 2008;and Alashker et al, 2010), reduced-order modeling approaches are generally preferable for simulating large-scale composite frames. Although a considerable amount of research has focused on reduced-order modeling of conventional reinforced concrete slabs, reduced-order modeling of ribbed composite slabs with profiled steel decking has received less attention.…”

“…However, for structural analysis of large-scale composite floor systems (see, e.g., Sadek et al, 2008), a relatively coarse mesh is preferable in order to reduce the computational burden. In this section, a sensitivity analysis is performed to study the effect of mesh refinement on the computed temperature distribution within composite slabs.…”

“…According to the principle of energy equilibrium, the energy equilibrium principle of deformation mechanics indicates that the work of external force is equal to the increment of kinetic energy, damping dissipation energy, and strain energy of the structural components, which can be written from Eq. (16).…”

“…The composite floor slabs as planar components have a bidirectional beneficial tension effect on the frame structures [15], which could enhance the ability of progressive collapse-resistant capacity of the structure through the tensile membrane action at the large deformations [16]. Although the recommended tie force(TF) method takes into account the catenary mechanism to describe the progressive collapse demand [3], it neglects the contributions of the membrane action of composite floor slabs at large deformations, which leads to the APM over-conservative and lack of sufficient theory and test data supporting.…”

“…Besides the beam-to-column connections, the modelling of the floor slab is also of great concern, since it can play a significant role in the structural resistance to progressive collapse. Khandelwal et al [9,10] and Sadek et al, [11] developed a reduced component connection model and simulated the composite slab in detail using LS-DYNA, which provided a useful insight into structural pushdown behaviour. However, this modelling approach is too complicated and computationally demanding for practical application in the design and assessment of structure for robustness.…”
