In this paper, mixed forced and natural convection heat transfer in a rectangular cavity has been numerically studied. the cavity receives a uniform heat flux from one side and is ventilated with a uniform external flow. The external flow enters the cavity from the heated side and leaves the cavity from the opposite side. The velocity and temperature fields and heat transfer rate are determined...

Up to now, a few formulas have been suggested by scholars for the amount of discharge from openings, however, the effect of opening's geometry on the amount of discharge has not addressed thoroughly. In this study, to assess the effect of rectangular openings’ aspect ratio on the discharge amount, experimental and numerical investigations have been conducted on the discharge amount from rectang...

This paper aims to study the behavior of steel I beams with web openings. However, openings might lead a noteworthy reduction in load-carrying capacity beams, but can also be so supportive and essential from an economic point view. An experimental investigation nonlinear three-dimensional finite element analysis using ABAQUS computer program were planned conducted on six I-beams having same dim...

steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...

This paper investigates the influence of an opening in infill steel plate on behavior trapezoidal corrugated panels. Two specimens shear walls were constructed and tested under cyclic loading. One specimen had a single rectangular opening, while other one two openings. In addition, percentage both was 18%. The initial stiffness, ultimate strength, ductility ratio energy dissipation capacity are...
