Experimental Investigation on the Structural Behavior of Shear Connectors Used in the FRP and Concrete Bridge Deck System

Abstract:

Feasibility study on the use of newly developed FRP and concrete composite bridge deck system is conducted. To lengthen the service life of bridge deck, the steel-free bridge deck system is developed. In this deck system, shear connectors between FRP module and concrete are utilized and structural behavior of shear connectors is investigated experimentally. The result of an investigation reveals that the system is promising.

An Experimental Study on the Shear Behavior of Perforated Shear Connector with Flange Head

Authors: Y.H. Kim, S.K. You, Jae Ho Jung, Soon Jong Yoon, Seung Sik Lee

Abstract: Concrete-steel composite members are formed by bonding a steel component, such as an I-section beam, to a concrete component, such as a reinforced concrete slab, so that the two components can act as a unit. The use of such type of composite member becomes main stream of construction technology since it provides efficient load resisting mechanism in structural system. In a composite member, bond between steel and concrete is a crucial factor for the composite action. Usually this bond behavior is achieved by installation of mechanical device so called shear connector. The composite action can be divided into two categories (i.e., full and partial) depending on the shear strength of mechanical shear connector embedded in the concrete, i.e., understanding of shear load resisting mechanism is necessary to develop a new shear connector for better, wider and more efficient application of composite action. For this purpose, the push-out tests are performed for the evaluation of several existing shear connectors including carefully designed perforated shear connector with flange head. One of the purposes of this experimental research is to define the shear resisting mechanism of the proposed new type shear connector. The experimental results show that the degree of composite action using perforated shear connector with flange head is superior to those of existing shear connectors such as a general headed stud, perfobond, etc. The experimental parameters, such as the number of perforated holes, the distance between perforated holes, and the height of shear connector, are carefully chosen for the verification of their effect on the capacity of shear resistance. From this experimental investigation it was found that the mechanical performance of proposed shear connector was efficient as a rigid shear connector.

Perforated FRP Shear Connector for the FRP-Concrete Composite Bridge Deck

Authors: Jeong Hun Nam, Soon Jong Yoon, Dong Min Ok, Sun Kyu Cho

Abstract: In recent years, the FRP-concrete composite bridge deck system has been introduced because of its light-weight and durability. The FRP-concrete composite bridge deck is composed of FRP module and concrete, and they are connected with shear connectors. In order to insure the composite action between FRP module and concrete, appropriate types of shear connector need to be installed. In this study, new type of FRP shear connector was suggested and the experimental investigations are conducted based on the studies of Perfobond. In the experimental study, the push-out test was conducted and the load carrying mechanism was analyzed including the friction effect of sand coating. Considering the load carrying mechanism of perforated shear connector under shear force, the empirical equation for the prediction of shear strength of perforated FRP shear connector was suggested.

Strength and Stiffness of Corrugated Rib Connector

Authors: Qing Tian Su, Dong Fang Wang

Abstract: Connectors are the key element in steel and concrete composite structure. To research and develop new type connector for steel and concrete composite structure, a new type connector, corrugated rib connector, was developed. The base mechanical properties of this connector were tested by push-out tests. The test results shown the mechanical properties of this connector are excellent. Comparing to the push-out test results of perfobond rib connector, the shear strength of corrugated rib connector increased 24 percent than that of the perfobond rib connector, and the shear stiffness of corrugated rib connector is larger than that of the perfobond rib connector, Especially the ductility of corrugated rib connector is 1.9 times that of the perfobond rib connector when they reach the ultimate load. Based on the load-slip relation of corrugated rib connector by push-out tests, relative stiffness expressions under normal service state and ultimate bearing capacity state are obtained.

Proposed Calculation Formula of Shear Connectors in UHPFRC-NSC Composite Structure

Authors: Yi Hong Guo, Zhen Qing Wang

Abstract: Shear connectors are usually used to connect two different structural materials and to transfer longitudinal shear forces across the materials interface in composite structures. This paper presents an experimental study on the behavior of shear connectors in UHPFRC-NSC composite structure. A new experimental installation (The NSC block is laid on the supporting deck, and the higher UHPFRC block is cantilever, meanwhile the top side of the NSC block is constrained.) is applied. A modified formula that it is proposed to calculate the load carrying capacity of shear connector is given. The experimental results are in good agreement with the calculated results.

Effect of GFRP Shear Ties on Shear Behavior of Interfaces between Precast Concrete Panel and Extruded Polystyrene Special Insulation

Authors: Seok Joon Jang, Young Chan You, Hyun Do Yun

Abstract: This paper describes the test results on the direct shear behavior of glass-fiber reinforced polymer (GFRP) shear tie reinforced interfaces between precast concrete sandwich panels (PCSP) and extruded polystyrene (XPS) insulations. The insulated PCSP consists of two concrete panels with 100mm or 80mm thick insulation between inner/outer concrete panel layers. In order to achieve composite action concrete panels are connected by corrugated GFRP shear connector. In this study, three types of couple replicate insulated PCSP with different embedment length of GFRP shear connector were made and loaded in push-out. The test results indicated that the reinforcement of GFRP shear ties for interface between PCSP and XPS insulation improves initial and post-peak shear performance of insulated PCSPs. These phenomena are remarkable for XPS insulated PCSPs with larger embedment length of GFRP shear connectors.
