Based on the application of a beam-column joint with replaceable energy-dissipating elements and hinged proposed by author, seismic performance fully assembled steel frame this was investigated in paper. Through two projects traditional (TSF) an applying joints (ASFWREE) their numerical simulation calculation SAP2000, main structural design indicators such as natural vibration period, period ra...

Modified-Partial Capacity Design (M-PCD) is proposed as one alternative of structural design methods. In M-PCD, the partial side sway mechanism where beams and some columns may develop plastic hinges. This method uses two models during process. The are used to simulate undamaged damaged structures when subjected earthquake (R=8.0) larger target (R=1.6) respectively. this study, 6- 15-story squa...

Abstract Many researchers have carried out experimental and numerical investigations to examine building structures’ response explosive loads. Studies of bridges subjected blast loads are limited. Hence, in this study, we present a case study on cable-stayed bridge, namely, Charles River Cable-Stayed Bridge-Boston, assess its robustness resistance against the progressive collapse resulting from...

In this paper, flexure hinges as the main part of the actuators frame are studied considering different profiles of flexure hinges and effective design parameters to introduce the best profile of the hinge based on the application that is needed. For this purpose five different profiles (right circular, elliptical, corner-filleted, hyperbolic and parabolic) of flexure hinges have been considere...

Recent condition of the earthquakes model has shown that rectangular concrete-filled tubes (RCFT) with weld connection are so brittle. According to studies conducted, large damages due cracking between beam flange and column face inducing concentrated stresses in this area. One novel alternatives reduce stress concentration at panel zone could be use section (RBS). Given enormous impact seismic...

A microactuating structure with vertical polyimide hinges has been designed, fabricated and tested. Unlike traditional microactuators, which are located on the substrate surface, this new actuation mechanism is capable of producing linear motion at a point far from the substrate. This advantage can make it possible to drive other out-of-plane folded structures for on-wafer or out-of-wafer appli...

The annual American Society of Plastic Surgeons’ “Plastic Surgery: The Meeting” is always filled with great educational events and endeavors, and the 2015 gathering in Boston was truly exceptional. Perhaps the most memorable and most rewarding panel that we had the honor and pleasure to be a part of was the Medical Student Session, moderated by one of the first Plastic and Reconstructive Surger...

Background A literature review did not reveal any study investigating the prevalence of depression among plastic surgery residents. Methods We conducted a cross-sectional mail survey and included all Saudi Plastic Surgery residents in our local program in Saudi Arabia. The Beck Depression Inventory II was used. Results The inventory showed that mild, moderate, and severe depressive symptoms...

Aesthetic plastic surgery is a branch of medicine using surgical techniques to alter the appearance of patients. In this paper it is considered whether aesthetic plastic surgery should be viewed as an art form. The question is answered by trying to see how aesthetic plastic surgery fits a number of classical concepts in philosophical aesthetics, concepts such as “artist” and “work of art”. Furt...

Randomized controlled trials are the gold standard of evidence-based medicine. In the field of plastic surgery, designing these studies is much more challenging than in pharmaceutical medicine. Randomized trials in plastic surgery encompass several road blocks including problems shared with other surgical trials: equipoise, high cost, placebo issues and learning curves following the establishme...
