Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

Background The SRS criteria give the methodological reference frame to present results of bracing. SOSORT criteria give the clinical reference frame for an appropriate bracing treatment. The combination of the two has never been presented in a study until now Objectives Verifying the efficacy of a complete conservative treatment of adolescent idiopathic scoliosis (AIS) according to the best met...

This paper investigates the applicabilty of an innovative bracing, called Articulated Quadrilateral (AQ) bracing system, which uses shape memory alloys (SMAs), for retroffiting low-rise to high-rise vulnerable SMFRs against strong ground motions. The paper investigates brace fundamental engineering characteristics, design of the system and also configuration of the brace (the proportion of SMA ...

The main girders of the I-section steel-concrete composite twin girder bridge is usually connected together by frame cross bracing. When with welding, flat plates for stiffening can be used to strengthen connection ensure effective transfer forces between two. In this paper, finite element simulation method study influence plates. results show that, compared structure without stiffening, when s...

Steel braced frame systems (SBFs) having high stiffness and strength are commonly utilized due to their resistance lateral seismic forces in regions with seismicity. In this study, concentrically frames (CBFs) different bracing configurations used obtain the significance of pulse period associated near-fault (NF) ground motion by time-history dynamic analysis. Besides, far-fault (FF) motions al...
