Due to architectural, mechanical and even structural considerations, in some cases there is need to create some openings in the composite steel shear walls. Presence of the openings can considerably affect the wall behavior. Therefore in this study, the effects of the opening on the behavior of composite steel shear walls are investigated. For this purpose, first an experimental specimen withou...

The purpose of this paper is to introduce the concept of partial rectangular metric spaces as a generalization of rectangular metric and partial metric spaces. Some properties of partial rectangular metric spaces and some fixed point results for quasitype contraction in partial rectangular metric spaces are proved. Some examples are given to illustrate the observed results.

Moonpool is an opening in the floor or base of a hull ship which can be used to lower tools and vehicles into the sea in a protected area. In this paper, the effect of a rectangular cross section moonpool on the resistance force of a supply vessel was investigated both by experimental and numerical methods. For both methods a 1:37.2 scale of Caspian3 surface vessel was used. Experiments were ca...

We characterize asymptotic collective behaviour of rectangular random matrices, the sizes of which tend to infinity at different rates: when embedded in a space of larger square matrices, independent rectangular random matrices are asymtotically free with amalgamation over a subalgebra. Therefore we can define a “rectangular free convolution”, linearized by cumulants and by an analytic integral...

In this study, nonlinear finite element (NLFE) analysis is conducted to determine the maximum shear capacity (Vmax) of stiffened steel plate walls (SSPSW) with rectangular openings. Results a wide range parametric study are presented using developed response surface method (RSM), which quantified effect prominent input variables on predicted SSPSW. The studied parameters, evaluated by different...

To develop a simplified and physically sound delamination-failure criterion, this paper reports joint experimental numerical study in which out-of-plane quasi-static indentations with different indentation forces were applied to the centre of fully clamped rectangular carbon fibre-reinforced polymer (CFRP) laminates. The results show that two basic micro-delamination growth modes, are separatel...

An experimental database of springback and twisting U-shaped elongated structures is available from a previous study. The materials are copper alloys: pure Cu, CuBe2, CuFe2P, provided in thin sheets thickness around 0.1 mm. After deep-drawing rectangular blanks, which can be aligned with the tools or slightly misaligned, tool withdrawal, structure exhibits an opening section (2D springback) (3D...
