Experimental and numerical study of the ductility of open-rib and reentrant composite slabs

Longitudinal shear strength design of composite slabs by full-scale FE modelling considering the embossments

“…After this bibliographical survey, it was possible to define the objective of this work as proposes the study of the failure mode by longitudinal shear in composite slabs by performing numerical analysis based on the Finite Element Method (FEM) with the consideration of the physical and geometric nonlinear behavior of the materials. In this context, this work proposes to combine and adapt a methodology developed at the Polytechnic University of Catalonia [12] to perform finite element simulations of four-point bending tests of composite slabs with steel deck, with explicit modeling of the geometry of the embossment, but modifying the embossments geometry to fit to a steel sheeting available in Brazilian construction sector, made of Brazilian steel standard ZAR280. For this purpose, the real dimensions of the steel sheeting were measured in situ, as will be illustrated in the next sections.…”

“…This work was developed using the methodology of numerical-computational simulation based on the finite element program ANSYS, version 2021R2, together with the programming language APDL (ANSYS Programming Design Language). It was used as a basis the methodology presented in the article by Soltanalipour et al [12] with adaptation for the materials of the construction market in Brazil, in order to include the geometry of a steel deck present in the Brazilian market (see Figure 2), considering the national regulations with the use of the provisions of the standards [1], [13], [14] and [15].…”

“…The parameters needed in ANSYS to define the concrete failure surface of Menétrey-Willam were the average uniaxial compressive strength (f cm ), uniaxial tensile strength (f t ), biaxial compressive strength (f bc ) and the dilatancy angle (ψ). The softening functions that apply after the compression and tensile limits have been reached were disregarded to avoid convergence difficulties in the nonlinear analysis [12]. The parameters used to represent concrete are shown in Table 2.…”

“…Gholamhoseini [11] in 2018 carried out a finite element analysis of a continuous composite slab with steel decking, but without explicitly considering embossments geometry. Soltanalipour et al [12] in 2022 modelled full-scale models explicitly including embossments via the ANSYS software, with steel sheeting available in Spanish construction sector, made of European steel standard S320. Besides explicitly modelling the embossments geometry, contact elements and a friction coefficient were also used to simulate the contact between both materials.…”

Study on Steel Content Estimation of Reinforced Concrete Rectangular Pool Wall

“…In the past research on structural design optimization, researchers have studied the structural optimization design of residential buildings, complex buildings, commercial buildings, and single-storey industrial buildings [3,4] and the reasonable steel content range of buildings by means of support vector machine method, genetic algorithm, statistical method, experimental and numerical study, etc. [9][10][11][12][13][14][15][16][17][18][19][20]. However, there is little report on the reasonable steel content for the minimal cost of water pools.…”
