Summary Although concentrically braced frames (CBFs) possess high lateral stiffness and strength, the buckling of compressive members indicates that a system does not have appropriate ductility. Therefore, CBF is successful for seismic regions. Comprehensive studies been performed on this drawback concerning systems. The use metallic damper considered an method to enhance behavior CBFs. While dampers improve hysteretic CBF, they impose additional costs structures. in study, steel damper,...
The unseating of decks is one the most prevalent failure modes bridges after earthquake events, as observed in 2010 Chile Earthquake. Damaged often had skew angles and were supported on elastomeric bearings. Similar bridge construction practices with bearings are also common central eastern U.S. (CEUS). seismic displacement demands skewed more complicated than those without due to coupling translational rotational mode vibration. study presented this article seeks understand response scope...
An innovative passive energy damper is introduced and studied experimentally numerically. This designed as the main plate for absorption which surrounded by an octagon cover. In addition to simplicity in construction, it can be easily replaced after a severe earthquake. Experimental test results, well finite element indicated that, connecting cross-flexural plate, mechanism of was changed from flexural shear. However, cross_flexural always acts mechanism. Changing shear mechanism, on other...
The global shear capacity of steel–concrete composite downstand cellular beams with precast hollow-core units is an important calculation as it affects the span-to-depth ratios and amount material used, hence affecting embodied CO2 when designers are producing floor grids. This paper presents a reliable tool that can be used by to alter optimise grip options during preliminary design stages, without need run onerous calculations. prediction formula developed using five machine learning...
Though concentrically braced frames pertain to high elastic stiffness and strength, their low ductility has been introduced as a no-desirable system in the seismic risk zone. Utilizing passive energy dampers capable economical idea, shortcoming can be solved. Experimental numerical studies on pipe confirmed satiable performance case of dissipating capacity. But, it is suffered from strength stiffness. To overcome these types metallic dampers, this paper, strengthening damper with shear...

Summary In current seismic design, structures that are essential for post‐disaster recovery, and hazardous facilities classified as risk category IV designed with higher importance factors stringent drift limits. These expected to perform better in an earthquake event because a larger base shear more limit used. Although this provision has been the design code over last three decades, few studies have investigated performance of structures. The aim study is quantify impact limits on steel...
Reinforced concrete shear wall is one of the most effective members during severe lateral loads especially in earthquakes and winds. Extensive researches, both analytical experimental, have been carried out to study behavior reinforced (RC) walls. Predicting inelastic response RC walls systems requires accurate, effective, robust model that incorporate important material characteristics behavioral features. In this study, a modeling method using fiber spring elements developed capture...
경계요소를 가지는 철근콘크리트 전단벽의 비선형 해석을 위한 간편 모델을 제안하였다. 이 모델은 휨 및 전단 거동을 스프링요소로 나타낸 거시적 모델이다. 휨거동은 벽체의 단면해석을 기초로 한 모멘트강도와 회전능력을 벽체 양단의 수직 나타내었다. 전단벽은 휨거동에 의해 지배되므로 전단거동은 바탕하여 변수를 계산하였고 중앙부 수평 제안된 전단벽 정적이력시험 결과와 비교한 후 비선형동적해석을 수행하여 사용된 이력법칙 변수들의 타당성을 조사하였다. 이용한 변수연구를 통하여 내진성능평가의 주요변수인 요구값과 성능값에 미치는 영향을 검토하였다. 그 결과 전단력-전단변형 관계에서 약간의 차이가 있지만 전체거동은 잘 일치하였으며, 주요 변수의 변화에 대해 성능값도 일정하게 변화하므로 해석모델은 가진 전단벽에 알맞은 것으로 판단된다. A simple model for reinforced concrete shear walls with boundary elements is proposed,...
The U10 undulator for the Pohang Light Source was measured with a pulsed wire measurement (PWM) method. By adjusting aperture of slotted optical switch (SOS) PWM, sensitivity SOS output to displacement improved significantly. A calibration table, which translates voltage wire, obtained and linearity PWM enhanced using this table. magnetic-field profile method agrees well that Hall probe mapping. effect dispersion on is also discussed.
