This paper introduces a new design form for prestressed shear walls with horizontal bottom slits utilizing cast-in-place technology. Horizontal are placed symmetrically at the wall-foundation interface of while concrete in middle wall width remains connected foundation. Furthermore, unbonded tendons inside adopted to provide self-centering ability. Tests on under cyclic loading were conducted investigate their seismic performance. Test results analyzed from tests, and comparison was made...
Bio-based phthalonitrile resins were synthesized using a two-step process. Initially, vanillin underwent nucleophilic reaction with nitro and potassium carbonate to form intermediates, which then dissolved in N, N-dimethylformamide. The intermediate was divided into two portions, 4,4’-oxydianiline 4,4’-methylenedianiline added each portion, respectively, produce different vanillin-based monomers: OVA monomer DVA monomer. successful synthesis of these bio-based monomers confirmed Fourier...
In this paper, a novel and simple method for predicting the peak response of RC beams subjected to impact loading is proposed. The theoretical basis calculating force originates from contact law, principle conservation energy, impulse‐momentum theorem, wave theory. Additionally, conventional beam theory, in conjunction with well‐known layered‐section approach, utilized obtain force‐deflection relationship beam. Subsequently, by taking into account strain rate effect, maximum midspan...
Reinforced concrete (RC) beams under the impact loading are typically prone to suffer shear failure in local response phase. In order enhance understanding of mechanical behavior RC beams, their dynamic and demand numerically investigated this paper. A 3D finite-element model is developed validated against experimental data available literature. Taking advantage above calibrated numerical model, an intensive parametric study performed identify effect different factors including velocity,...
Abstract The dynamic behaviour of a system three‐dimensional, massless, rigid, surface foundations arbitrary shape perfectly bonded to the elastic half‐space is numerically studied with frequency domain boundary element method. This method employs Green's function for and this results in discretization only soil‐foundation interfaces. In addition, use isoparametric quadratic quadrilateral elements increases accuracy method, which confirmed by comparison other known numerical solutions....
Because the seismic performance of steel reinforced concrete (SRC) members are usually different from that common members, a modified Park-Ang damage model for SRC is proposed in this paper. The combination coefficient derived using related experimental results columns. Then, formula developed to describe relationship between and parameters columns such as axial load ratio, ratio slenderness radio. indicate at failure state index has mean value close 1.0 limited scatter. response can be...
Abstract Many reinforced concrete or steel single‐tower buildings have been built in China. The structural performance of such one‐tower systems depends on that the primary components are walls moment‐resistant frames. For multi‐tower connected structures, problems become more complex. A building, with large floor slab openings plan and long‐span truss elevation, was thus studied because its complexity irregularity. First, a 1/25 scaled model structure tested shake table under minor,...
AbstrctFor a vertically mixed structure composed of two parts, lower part made concrete and an upper steel, the damping matrix is non-proportional.

First, steel-concrete simulated by SDOF-SDOF oscillator first characteristics each subsystem. The are plotted as functions mass frequency subsystems. predicted MSE confirmed exact time history analysis under...
A combined boundary and finite element method is developed applied to study the dynamic behaviour of a system flexible surface footings arbitrary shape bearing on an elastic half-space. The proposed employs frequency domain Green's function for half-space while layered plate model used footing. Both footing are discretized by 8-noded quadratical isoparametric elements, meshes identical. Thus, compatibility displacements equilibrium forces between fully satisfied. This provides better...
This article investigates the shear strength of steel plate reinforced concrete wall under cyclic loads.
