RISBehaviors and Modeling of New Self-Centering RC Wall with Improved Disc Spring Devices
Publisher: ASCE
Abstract: Cyclic loading tests were conducted on self-centering reinforced concrete (RC) walls with disc spring devices (SC-RCW-DSD), and results confirmed that these walls had sufficient energy dissipation and satisfactory ...
Cyclic Behavior of Corrugated Double-Skin Composite Walls with Different Aspect Ratios
Publisher: ASCE
Abstract: Experiments and finite element (FE) simulations were conducted on corrugated double-skin composite (Co-DSC) walls consisting of concrete-filled steel tubes (CFTs) and corrugated steel faceplates connected by tie bolts with ...
Modeling of Magnetorheological Self-Centering Brace
Publisher: ASCE
Abstract: The self-centering brace (SCB) is a high-capacity structural component for lateral force resistance and recentering. This paper focuses on modeling the magnetorheological self-centering brace (MR–SCB). Full-scale cyclic ...
Seismic Assessment of Buildings with Prepressed Spring Self-Centering Energy Dissipation Braces
Publisher: ASCE
Abstract: The seismic performance of four- and eight-story steel buildings with prepressed spring self-centering energy dissipation (PS-SCED) braces was evaluated using a proposed nonlinear mechanical model. Nonlinear dynamic analyses ...
Experimental Investigation on the Seismic Behavior of a New Self-Centering Shear Wall with Additional Friction
Publisher: ASCE
Abstract: In this work, a new self-centering shear wall with disc spring devices (SCSW-DSD) was developed and experimentally verified. The proposed SCSW-DSD was a combination of a reinforced concrete (RC) wall and two disc spring ...
Seismic Behavior and Design Approach of Variable-Damping Self-Centering Braced Frame
Publisher: ASCE
Abstract: In this paper, the seismic performance and resilience of a 15-story variable-damping self-centering braced frame (VD–SCBF) were analyzed. The interstory drift ratios (IDRs) of the VD–SCBF are similar to those of the ...
Modeling of Disc Spring Self-Centering Energy Dissipation Braces from Inactive State to Design Limit State
Publisher: ASCE
Abstract: This paper focuses on modeling the hysteretic behavior of disc spring self-centering energy dissipation braces (DS-SCEDBs) from the inactive state to the design limit state, and proposes two restoring force models for ...
Development of a Concrete Constitutive Model Considering Free Water Effect for Predicting Dynamic Responses of Concrete Structures
Publisher: ASCE
Abstract: Existing research indicates that free water has a considerable influence on the dynamic mechanical properties of concrete, which is not considered in commonly used concrete models. This paper presents a high-fidelity ...
Experimental Studies on Mitigating Local Damage and Fragments of Unreinforced Masonry Wall under Close-in Explosions
Publisher: American Society of Civil Engineers
Abstract: Debris hazard causes most of the casualties and injuries in terrorist or accidental explosions. It is defined as high-velocity fragments originating from structural components and building envelope systems induced by a ...
