Comparative study of energy dissipation capacity of steel and glass fibre-reinforced polymer frames with bonded sleeve connections

Abstract

This paper presents a comparative study on the energy dissipation capacity of one glass fibre-reinforced polymer frame with bonded sleeve connection and steel frames with bolted endplate connections. Experimentally measured moment-rotation behaviour of a typical bonded sleeve connection was employed to develop the joint model for the glass fibre-reinforced polymer frame. In order to reduce the effect of the different beam size on the overall frame behaviour, the size of the steel profiles was selected to be equal, less than and greater than glass fibre-reinforced polymer profile in terms of the bending stiffness. The moment-rotation response of bolted endplate connection was then theoretically determined through Mohammadi's design model. The frame models were developed using 3D beam elements and nonlinear spring elements. Comparing the energy dissipation capacity between glass fibre-reinforced polymer and steel frames at connections and floors, it was found that although glass fibre-reinforced polymer members were lack of ductility, the glass fibre-reinforced polymer frame can give satisfactory energy dissipation capacity that is comparable to steel frames. The energy dissipation capacity of glass fibre-reinforced polymer frame can be induced by the yielding of steel endplate from bonded sleeve connection.

Mechanical Characterisation of GFRP Frame and Beam-to-Column Joints Including Steel Plate Fastened Connections

“…The facades and the horizontal elements are implemented by adopting the “Wall E+ ®® construction system”, innovative building system made with pultruded GFRP blocks, specifically designed to be adapted to the different required geometry allowing a wide range of possibilities in the openings setting, characterised by excellent thermal and acoustic insolation properties and conceived in line with sustainability principles [ 21 ]. Concrete is poured onto the prefabricated elements of the deck in order to obtain a rigid slab and to reduce the vibrations of the system.…”

“…For this reason, several studies were carried out to experimentally characterise joints between FRP structural elements, including bolted or riveted solutions comprising FRP or steel connecting elements [ 18 , 19 , 20 ]. These studies, combined with numerical applications, emphasised the importance of an accurate definition of the moment–rotation properties of the joint in order to have a reliable prediction of the frame’s mechanical behaviour [ 21 , 22 ]. It also highlighted the need of comparing the mechanical performance of FRP structural elements with serviceability and ultimate limit states to show the suitability of the material for designing purposes [ 23 , 24 ].…”

Influence of clearance and type for bolt holes on mechanical behavior of bearing-type bolted FRP connection

“…Bolted connection is a common connection method for FRP structures and it has the advantages of economy, convenience of construction, ease to replace, low environmental sensitivity, and low requirements for surface treatment [1][2][3]. However, because FRP material has almost no plastic deformation capacity, the seismic performance of FRP beam-column joints is poor [4][5]. Garl Edward Grigorian [6] studied the energy dissipation with slotted bolted connections(SBCs) and found that it has excellent energy dissipation capacity.…”
