During a baseball game, the ball will strike the playing surface at a variety of speeds and angles. The speed at which the ball travels after impact with the playing surface has been referred to as the pace of the surface. Wide variations in pace can reduce the safety and playability of baseball field surfaces. Pace can be quantified by measuring the coefficient of restitution. The coefficient ...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...

This study aims to investigate the effect of infilled frames through various important parameters (i.e., openings’ percentage in infill walls - several columns on first floor are removed partial infilled) RC structures, subject progressive collapse scenarios. To this end, 3D finite element models were constructed by using software ABAQUS. Numerical and experimental results compared substantiate...

Abstract This paper focuses on the optimum design of e-CLT technology. The technology consists in adding cross laminated timber (CLT) walls to an existing reinforced concrete (RC) infilled frame via asymmetric friction connection (AFC). authors carried out quasi-static and nonlinear dynamic analyses. RC is modeled OpenSees by fiber-section-based elements with force-based formulation. contributi...

Taking into consideration the seismic vulnerability and poor energy performance of European building stock, increasing socio-economic environmental need for integrating upgrading with efficiency improvement, an experimental study involving lateral load testing full-scale one-story one-bay masonry infilled RC frames load-bearing walls was carried out in framework SupERB research project aiming t...

The proposed study examines the propagation of uncertainty associated with angle seismic incidence a group ground motions, as well to that motion size, expected loss estimates reinforced concrete buildings. Six buildings infilled frame systems are studied, representative non-seismically designed structures typical southern European practice. Their monetary losses computed using performance-base...

This study focused on characteristic cases of recently tested real-scale RC framed wall infilled structures with innovative seismic protection through polyurethane joints (PUFJ) or polyurethane-impregnated fiber grids (FRPU). The frames revealed a highly ductile response while preventing infill collapse. Herein, suitable 3D pseudo-dynamic FE models were developed in order to reproduce the exper...
