“…All rebars which are used in their tensile area and only in the S320c model, in addition to the tensile bars, compression bars are also used. The compressive strength of concrete is 32.50 MPa (Brunesi and Nascimbene, 2015). The static loading is applied surface to 100 N/cm 3 on certain slab surfaces.…”

Due to the high seismicity of our regions, engineers have always sought to provide various solutions to improve the performance of buildings and consequences control of powerful earthquakes. Building Lighting is one of the methods used to reduce earthquake forces. The use of prefabricated slabs is one of the ways to reduce the dead load of a building. In this study, four types of prefabricated slabs with different thicknesses under a certain dead load have been modeled in ABAQUS Software. By analyzing nonlinear static analysis, slab capacity and nonlinear behavior are evaluated. The results show that by increasing the thickness of the slab, the shear strength of the slab increases. The results also show that the ultimate strength has been reduced in a hollow slab with polygon holes (non-circular).

“…1, the rebar diameter used in the slab is 125 mm. The mesh used in the model are prestressed, with a force equal to 11,000 kg/cm 2 (Brunesi and Nascimbene, 2015). All rebars which are used in their tensile area and only in the S320c model, in addition to the tensile bars, compression bars are also used.…”

“…2 shows isometric and plan views of a representative building model used for damage analysis through distributed-plasticity approach and pushdown simulation techniques. While high-definition solid FE models based on classical principles of nonlinear fracture mechanics [53][54][55] represent an attractive solution for interpreting the evolution of crack patterns and damage mechanisms of RC structures at a local level [25,33,34], fiber-based idealizations were shown to be a transparent and viable approach to accurately characterize the inelastic response of such building typology in a computationally efficient manner [32]. To this aim, the open FE platform SeismoStruct [56] was adopted to prepare 2D and 3D models of EC2-compliant and EC8-compliant structures and to play out the series of pushdown analyses explicitly including material and geometric nonlinearities.…”

“…Based on the assumption of small deformation and plane section, fiber element method [20,21] is widely used in numerical analysis and has been verified to be effective to assess nonlinear response of braced frames [22 -26] and evaluating the capacity of precast-prestessed slabs [27,28]. This method is suitable to different sections since it discretizes the cross-section into fibers.…”

Abstract:In order to investigate the seismic performance of reinforced concrete frame with unequal span, a specimen was tested under low-cyclic loading and the seismic performance of this frame was analyzed based on fiber element method using software OpenSees. Hysteretic curves, skeleton curves, ductility, stiffness degradation and energy dissipating capacity of the frame are compared and analyzed. The experimental and simulate results demonstrate that this frame has a poor seismic performance. Thus, it is suggested that the seismic strengthening criteria of unequal-span frame structure should be raised and the existing buildings of this structure should be retrofitted.
