Abstract: Reinforced concrete (RC) structures with weak or soft stories have exhibited poor seismic performance in several past earthquakes, primarily due to high seismic force and deformation demands on the columns in these soft ...

Abstract: The design of connections of gusset plates, beams, and columns of concentrically braced frame systems is typically based on the forces generated by brace actions without considering the frame actions. This may result in ...

Abstract: Hybrid double-skin tubular columns (DSTCs) are a promising form of composite columns in which the concrete is sandwiched between inner steel and outer fiber-reinforced polymer (FRP) tubes. A modified form of DSTC incorporating ...

Abstract: This paper presents an experimental investigation to study the influence of the type of end connections as well as the detailing of end-protected zones on the seismic performance of special concentrically braced frames ...

Abstract: Seven full-scale concrete beam specimens are tested under gradually increasing monotonic loading to investigate their overall flexural response due to the addition of both metallic and nonmetallic fibers to the concrete. ...

Abstract: Buckling-restrained braced frames (BRBFs) are often used as primary seismic force resisting systems to achieve the desired seismic performance of building frames. However, significant residual displacements of these systems ...

Abstract: The poor seismic response of gravityload-designed reinforced concrete (RC) frames with a soft story can be effectively controlled by using metallic dampers as passive energy dissipation devices. However, the absence of ...

Abstract: Basalt fiber–reinforced polymer (BFRP) has been the most recent fiber–reinforced polymer (FRP) composite material introduced as reinforcement and prestressing tendons for concrete. Measuring the mechanical properties of ...

Abstract: Hybrid columns with partial structural steel-reinforced concrete (SRC) and reinforced concrete (RC) sections in the transfer stories of buildings are prone to premature shear failure due to sudden changes in load bearing ...

Abstract: A test program on cold-formed steel (CFS) laced columns fabricated using plain channels has been presented in this study. Twelve specimens with single and N-type lacing configurations were fabricated. The lacing plates and ...
