In this paper, the stress concentration around a hole in the single layer composite materials with long fibers is examined. The single layer has an infinite length, limited with and instant thickness and is loaded by a constant tension force p at infinity. The width of the lamina is considered to be finite and bears a hole as a defect. Due to presence of excessive shear stress in the matrix bay...

This paper aims to develop a numerical model of RC frame considering the same geometrical properties, material properties and boundary conditions in ABAQUS validated with experimental results comparing its force-displacement curve, damage pattern stress strain variations outcomes. The use infill walls increases progressive collapse resistance force, mainly CAA. is due addition compressive actio...

An improved numerical model that can simulate the nonlinear behavior of reinforced concrete beams subjected to blast and impact loadings is introduced in this paper. The layered section approach is based in the formulation, and the dynamic material behaviors of concrete and steel are defined with the use of the dynamic increase factor. Unlike the classical layered section approach that usually ...

We study the problem of combined bending and tension an isotropic plate containing a through crack by distributed moments forces at infinity in absence contact between faces external loads applied to but presence plastic zones its tips. also take into account phenomenon hardening material satisfying Tresca plasticity conditions form surface layer or hinge. By using complex potentials plane clas...

This study investigates the complex load-bearing mechanism of reinforced concrete tower large wind turbines through a structural model test. MTS electro-hydraulic servo loading system was used to load two models for push-out The ultimate bearing capacity found be 8.894 kN. test findings revealed that top is subjected unilateral shear as horizontal increases. As result, strain in compression zon...

The application of CFRP tendons in precast segmental concrete beams (PSCB) as internal un-bonded prestressing reinforcement is a newly developed scheme to improve structural flexural performance. stress increment the tendon, depending on whole deformation, crucial value be predicted for capacity design. Due discontinuity opening joints, deformation modes differ from monolithic ones. existing pr...
