چکیده

An innovative concept for normalizing the multiple seismic performance objectives of retrofitted structures was recently introduced by the authors. Referred to as a damping-enhanced strengthening, this integrated damping and strengthening strategy included the bonding component between FRP sheets and viscoelastic layers as well as the anchoring component of FRP sheets into concrete. Although anchorage of FRP sheets into concrete with FRP rods was successful in some applications, their joint behaviour under static and dynamic loading needs to be evaluated systematically. This paper presents an experimental research program on the bonding and anchoring characterization among FRP sheets, concrete surface, and viscoelastic layers. The effects of temperature and load rate on the joint properties are investigated. A simple analytical model is proposed based on the ACI design equation.

An Integrated Frp Strengthening and Damping System for Multiple Performance Level Seismic Retrofit of Rc Columns

The concept of an integrated strengthening and damping retrofit system was proposed to design reinforced concrete (RC) columns for their optimal performance under multi-level earthquake hazards. As illustrated in Figure 1, the system consisted of fiber reinforced polymer (FRP) sheets wrapping around a column and viscoelastic (VE) layers on the FRP sheets. The motion of the outer surface of the ...

Analysis of Masonry Infill Panels Retrofitted with FRP Sheets in R/C Frames

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...

Flexural Strengthening of Concrete Slabs by a Three-stage Prestress- ing FRP System Enhanced with the Presence of GFRP Anchor Spikes

Some of the advantages that results from the structural strengthening of concrete slabs using prestressed fiber reinforced polymer (FRP) systems are as follows: the prestressed FRP delays the formation and propagation of cracks, and both the serviceability and the flexural capacity are increased. In this research program, the flexural performance of a concrete slab strengthened with a three-sta...
