This paper aims to examine the seismic response of prestressed self-centering moment-resisting frames (PSC-MRFs) based on concrete-filled double steel tubular (CFDST) columns and RC beams. The beam of this novel connection is divided into two parts. connected by bolts and tendons. and the beam includes a gap opening feature. https://www.spidertattooz.com/WAC-4011-LED-Horizontal-Step-Light-Colorscaping/
