The primary seismic force-resisting system (SFRS) in middle- to high-rise reinforced concrete (RC) building structures often includes coupled shear walls (CSWs) and single (SSWs). These are designed transfer lateral forces the foundation dissipate energy through development of plastic hinges. latter lead residual displacement these structural components. On other hand, self-centering systems en...
AIMS Current imaging techniques attempt to identify responders to cardiac resynchronization therapy (CRT). However, because CRT response may depend upon several factors, it may be clinically more useful to identify patients for whom CRT would not be beneficial even under optimal conditions. We aimed to determine the negative predictive value of a composite echocardiographic index evaluating atr...
This paper provides a simplified tool for preliminary seismic assessment of the out-of-plane behavior non-structural walls, such as unreinforced masonry partition based on non-linear time-history analyses. The studies are performed using equivalent single-degree-of-freedom systems and trilinear hysteretic models. stability is investigated through statistical computed displacement demand related...
The ORNL Ultra-Small-Angle Neutron Scattering (USANS) facility at the High Flux Isotope Reactor (HIFR) has been recently upgraded, using the BonseHart technique. Si(111) triple-bounce channel-cut single crystals have been used for both the monochromator and analyzer. The total width of the rocking curve of the analyzer is about 1.6" and the wavelength of the primary neutron beam is 2.59 ,~,. It...
Controlled rocking steel braced frames (CRSBFs) are modern systems for resilient building structures known their effective energy dissipation and self-centering features. In a CRSBF, post-tensioned (PT) strands shear fuses the distinct features providing mechanisms. As relatively new structural system, there is need to study this system’s optimal design. Control co-design has gained interest in...
Abstract This paper presents an innovative anti-seismic device for controlling the out-of-plane rocking motion of masonry walls with traditional tie-rods, called LInear COntrolled Rocking Device (LICORD). LICORD is a low-impact box connected to extremity tie-rod designed mitigate medium–high intensity earthquakes. Additionally, widens knowledge about dynamic behavior through interpretation resu...
