Performance of Perforated Plate Column without Downcomer

TOPOLOGY OPTIMIZATION OF PERFORATED STEEL PLATE SHEAR WALLS WITH THICK PLATE IN SIMPLE FRAMES

In this paper, topology optimization (TO) is applied to determine the form, size and location of holes for the special form of perforated steel plate shear wall (PSPSW). The proposed model is based on the recently presented particular form of PSPSW that is called the ring-shaped steel plate shear wall. The strain energy is selected as the objective function in the optimization. Simple Isotropic...

Experimental and Numerical Study of Perforated Steel Plate Shear Panels

Thin perforated Steel Plate Shear (SPS) Walls are among the most common types of energy dissipating systems. The applied holes reduce the shear strength of the plate and allow to decrease the profile size of the members at the boundary of the panel when these systems are used in the typical design of structures. On the other hand, the different fracture locations of these panels are visible whe...

Green dialysate: asymptomatic perforated cholecystitis without peritonitis.

In peritoneal dialysis, the effluent dialysate is the window of the peritoneal cavity and usually allows for a rapid diagnosis of peritonitis and abdominal drama [1]. To our knowledge, there is only one reported case of perforation of the gallbladder in a patient on peritoneal dialysis with gram negative peritonitis [2]. We describe a case of asymptomatic perforated cholecystitis without perito...

Mass Transfer Coefficients in Pulsed Perforated-plate Extraction Columns

This study examined the mass transfer performance in a pulsed perforated-plate extraction column with diameter of 50 mm using two different liquid systems. Mass transfer coefficients have been interpreted in terms of the axial diffusion model. The effects of pulsation intensity and dispersed and continuous phase velocities on the mass transfer performance have been investigated. Three different...
