Aiming at the fatigue cracking of steel bridge deck pavement and shortage river sand resources, a sea RPC scheme was proposed. Taking Quanhe box girder as research background, simulation model established by using ANSYS finite element software, mechanical analysis RPC-asphalt composite structure carried out to determine most unfavorable load position. A three-point test study performance specim...

Several efforts were made over the years to control vibration of structural components made of composite materials. This paper consists of study on effect of using shape memory alloy (SMA) to increase the damping of glass fiber reinforced plastic (GFRP) composites. A comparative study between SMA and steel was made as reinforcement material in GFRP composites to enhance damping. Dimensions of e...

This paper presents a simplified approach for the design of semi-continuous composite beams in braced frames, where specific attention is given to the effect of joint rotational stiffness. A simple composite beam model is proposed incorporating the effects of semi-rigid end connections and the non-prismatic properties of a 'cracked' steel-concrete beam. This beam model is extended to a sub-fram...

The damage identification study presented in this article leveraged a full-scale sub-component experiment conducted in the Charles Lee P owell Structural Research Laboratories at the University of California, San Diego. As a payload project attached to a quasi-static test of a full-scale composite beam, a high-quality set of lowamplitude vibration response data was acquired from the beam at var...

Abstract The objective of this study is to analytically assess the effectiveness a novel composite rubber bearing (CRB), which proposed enhance both displacement and damping capacities laminated natural (LNB), in improving seismic performance girder bridges. Four numerical bridge models respectively with unbonded bonded LNBs CRBs (i.e. ULNB, BLNB, UCRB, BCRB) are established based on restoring ...
