RISSeismic Response of Full-Scale Structure with Added Viscoelastic Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper presents the test and analytical results of a full-scale 5 story steel frame with added viscoelastic (VE) dampers. The ISD110 VE dampers made by 3M Company are installed to the long (East–West) direction of the ...
Strain Rate Effect on Structural Steel under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The strain rate and strain rate history effects on the inelastic stressstrain behavior of annealed A‐36 structural steel at room temperature are examined experimentally under monotonic and cyclic loading conditions. The ...

Publisher: American Society of Civil Engineers
Abstract: This paper presents the experimental and analytical results of a shaking-table study on the elastic and inelastic behavior of a
Active Control with Optical Fiber Sensors and Neural Networks. II: Experimental Verification
Publisher: American Society of Civil Engineers
Abstract: Experimental results for a full-scale steel frame structure with a smart active control system under shaking-table testing are presented. To this end, a full-scale steel frame structure with the proposed control system is ...
Long-Term Deflection Control in Cantilever Prestressed Concrete Bridges. I: Control Method
Publisher: American Society of Civil Engineers
Abstract: Creep and shrinkage of concrete may lead to excess long-term deflection in concrete members, especially in prestressed concrete structures. The long-term vertical deflection of a segmentally constructed prestressed concrete ...
Long-Term Deflection Control in Cantilever Prestressed Concrete Bridges. II: Experimental Verification
Publisher: American Society of Civil Engineers
Abstract: This paper continues the preceding study on the long-term deflection control of prestressed concrete bridges. In this paper, an experimental study is first presented. The objectives of the experimental program are to check ...
Experimental Testing and Numerical Simulation of Precast Segmental Bridge Piers Constructed with a Modular Methodology
Publisher: American Society of Civil Engineers
Abstract: A new precast segmental bridge pier system using modular construction methodology is proposed in this study. The proposed system contains multiple segmental layers with several small precast modular RC segments for each ...
Compressive Behavior of Steel-Fiber-Reinforced Concrete with a High Reinforcing Index
Publisher: American Society of Civil Engineers
Abstract: Compression tests on cylinders were performed to characterize the compressive stress-strain behavior of steel fiber-reinforced concrete (SFRC) with a high reinforcing index. The reinforcing index, defined as the product ...
