RISFlexural Behavior of Circular Concrete Filled FRP Shells
Publisher: American Society of Civil Engineers
Abstract: A new structural system has been developed that combines a fiber-reinforced polymer (FRP) shell with a concrete core for use as bending members in civil structural applications. The external fiber-reinforced shell in this ...
Influence of Inelastic Tower Links on Cable-Supported Bridge Response
Publisher: American Society of Civil Engineers
Abstract: A new concept for bridge tower designs in seismic zones incorporates sacrificial link schemes that enable the tower shafts to remain elastic under large seismic excitation. In order to study the influence of inelastic tower ...
Stress Measurement and Defect Detection in Steel Strands by Guided Stress Waves
Publisher: American Society of Civil Engineers
Abstract: Health monitoring of steel strands is the subject of much research in the nondestructive evaluation and civil engineering communities. This paper deals with a guided stress wave method for stress monitoring and defect ...
External FRP Poststrengthening of Scaled Concrete Slabs
Publisher: American Society of Civil Engineers
Abstract: This research investigates the effect of externally bonded fiber-reinforced polymer composite strips and fabric to the soffit of scaled slabs. Thirteen slabs of size 2,290 × 480 × 102 mm were tested to failure with varying ...
Poststrengthening of Concrete Slabs: Full-Scale Testing and Design Recommendations
Publisher: American Society of Civil Engineers
Abstract: This paper reports on an experimental research project concerning the poststrengthening of concrete slabs with externally bonded carbon fiber reinforced polymers (CFRP). The two problems studied were strengthening in order ...
Cyclic Testing of Built-Up Steel Shear Links for the New Bay Bridge
Publisher: American Society of Civil Engineers
Abstract: Tests were conducted on two prototype steel shear links for the main tower of the new San Francisco-Oakland Bay self-anchored suspension bridge to evaluate the link force and deformation capacities. The links were built-up ...
Seismic Retrofit of RC Columns with Continuous Carbon Fiber Jackets
Publisher: American Society of Civil Engineers
Abstract: The development, the validation, and the implementation of a new seismic retrofit system for reinforced concrete columns are described. The column jacketing system consists of continuous carbon fiber prepreg tows wound in ...
Assessment of a Steel-Free Fiber Reinforced Polymer-Composite Modular Bridge System
Publisher: American Society of Civil Engineers
Abstract: The paper describes the development and characterization of a modular bridge system incorporating fiber reinforced polymer (FRP) composite girders connected by stiffened FRP deck panels which serve as both formwork and ...
Experimental Performance of Concrete Columns with Composite Jackets under Blast Loading
Publisher: American Society of Civil Engineers
Abstract: Measures to prevent progressive collapse of structures include protection of critical elements such as columns. In support of this goal, nine tests were conducted to assess the as-built performance of typical columns and ...
