Steel H-beams with corrugated webs can provide high shear buckling resistance with very thin webs, which results in saving steels. Common beam-to-column rigid connections are not suitable for H-beams with corrugated webs, so two types of beam-to-column connections are proposed for H-beams with corrugated webs. One beam-to-column connection is to weld a short cut of the common H-beam at the end of the H-beam with corrugated webs, and the other one is bolted endplate connection. To investigate the hysteresis behavior of the beam-to-column connections of H-beam with corrugated webs, four specimens of the two types of connections were tested. Failure modes and hysteresis loops were obtained. The failure modes of the specimens were all shear buckling of the corrugated webs, and no failure was found at the connection parts. The specimens with initial imperfection showed early buckling in the tests. The test results revealed that the two types of the beam-to-column connections of H-beams with corrugated webs had good cyclic performance without brittle failure, and that the initial imperfection of the corrugated webs influenced the hysteresis behavior of the connections. © 2016 Taylor & Francis Group, London.

In this paper, a three-dimensional beam element is developed for geometric nonlinear dynamical analysis. This element is based on the co-rotational formulation, in which the displacements of beam element are subdivided into rigid body movements and elastic deformations. The formulations are derived from the continuum mechanics based Updated Lagrangian incremental equations. The element can undergo large deflections and rotations, but small strains are assumed in the deduction. The validity of this element is confirmed by comparing with the numerical results in other literatures. © (2014) Trans Tech Publications, Switzerland.

This paper investigates the ductility of SIFCON blocks with various structural measures adopted to further increase their ductility. Ten SIFCON blocks with various designs were tested using a compression machine to investigate their ductility. The variables examined included fiber alignment, confinement, perforation, and longitudinal bars. Results of the tests indicated that SIFCON blocks with confinement in the form of stirrups and additional perforation can produce better ductility than others. © (2014) Trans Tech Publications, Switzerland.

Closed form solutions are derived in this work by including free end slip, relating free end and loaded end slips to bond resistance, as well as relating slip or strain at any position to free end slip. To identify the bond-slip relationship, indirect analytical identification from load-slip response curve is used. Using the identification procedure developed in this paper, very good agreement between the theoretical solutions and experimental results was observed, which validates the theoretical results derived in this work. © (2013) Trans Tech Publications, Switzerland.

Pure adhesive bond of FRP to concrete is not only weak but also unreliable in a long term. This problem can be effectively overcome by a newly developed bond enhancement system - the hybrid bonded FRP system (HB-FRP) - in which small mechanical fasteners are used to augment the bond. In this paper, the bond behaviors of EB-FRP and HB-FRP joints were experimentally investigated by employing the single shear pull-off test on three EB-FRP and seven HB-FRP specimens with different bond lengths. Experimental testing is reported for characterization of the interfacial bond of the HB-FRP system. © (2013) Trans Tech Publications, Switzerland.

A comfort analysis for the buildingat a metro depot is presented in this paper with FEA method. First, the dynamic analysis for the whole building structure is performed and the acceleration responseofeach floor is calculated and compared with the civil codes, based on which the structuralcomfortis estimated. And then, the major factor resulting in the comfort problem of shear-wall buildings is obtained by frequency domain analysis and it is the summation of mode participatingcoefficientsaccording to the peak-amplitude frequency-range of vibration source. And finally, an advice for the modification of buildingdesignis presented to avoid the structural comfort problem. © (2014) Trans Tech Publications, Switzerland.

This paper investigates the ductility of beams with slurry infiltrated fiber concrete (SIFCON) blocks. Three SIFCON blocks with confinement in the form of stirrups and additional perforation were tested in a beam where a SIFCON block was placed into the plastic hinge zone of the beam as a compression yielding material. Results of the tests indicated that SIFCON blocks with confinement in the form of stirrups and additional perforation can produce sufficient ductility for compression yielding system. © (2014) Trans Tech Publications, Switzerland.

Pure adhesive bond of FRP to concrete is not only weak but also unreliable in a long term. This problem can be effectively overcome by a newly developed bond enhancement system - the hybrid bonded FRP system (HB-FRP) - in which small mechanical fasteners are used to augment the bond. In this paper, theoretical modeling is reported for characterization of the interfacial bond of the HB-FRP system. Local bond-slip model involving adhesive and mechanical mechanisms is proposed. Based on the basic bond-slip model, load-slip response, ultimate bond strength, and effective bond length of the HB-FRP bond interface are obtained by analytical or numerical solution. Good agreement between the analytical and experimental results indicates that the proposed bond-slip model can well predict bond behaviors of HB-FRP joints. © (2013) Trans Tech Publications, Switzerland.

Gypsum walls are a green product that helps to save energy and protect the environment. This paper investigates the shear strength of glass fiber reinforced gypsum (GFRG) walls fully or partially filled with concrete in the hollow cores. Eight full scale GFRG walls were tested. The shear performance of the tested walls, including the shear failure mode, hysteresis responses, the ultimate shear strength were studied in the paper. A design procedure for the shear strength of the concrete filled GFRG walls is developed. © (2013) Trans Tech Publications, Switzerland.

Gypsum walls are a green product that helps to save energy and protect the environment. This paper numerically investigates the effect of axial load on shear strength of glass fiber reinforced gypsum (GFRG) walls fully or partially filled with concrete in the hollow cores. The conclusion drawn in this paper is general and applicable to other kinds of walls. © (2013) Trans Tech Publications, Switzerland.
