RISDrift Ratio Limit States for Circular Concrete Columns Reinforced with Different Types of High-Strength Steel Reinforcing Bars
Publisher: ASCE
Abstract: A prime reason for the restricted use of high-strength steel (HSS) rebar as the main reinforcement in concrete columns in seismic regions is the lack of appropriate seismic design guidelines. Within the context of ...
Lateral Cyclic Response of RC Bridge Piers Made of Recycled Concrete: Experimental Study
Publisher: ASCE
Abstract: Using recycled coarse aggregate (RCA) in construction reduces the negative environmental impacts that are associated with new concrete production. However, few studies have investigated the structural performance of bridge ...
Incremental Dynamic Analysis–Based Procedure for the Development of Loading Protocols
Publisher: ASCE
Abstract: Seismic assessment is of critical importance for structures in regions where earthquakes are prevalent. Such assessment in terms of determining the inelastic capacity of structures is often performed in laboratories of ...
Comparative Study on Seismic Fragility Assessment of Self-Centering Energy-Absorbing Dual Rocking Core versus Buckling Restrained Braced Systems under Mainshock–Aftershock Sequences
Publisher: ASCE
Abstract: A strong mainshock may cause several aftershocks within a short interval. These aftershocks can make buildings damaged during the mainshock more vulnerable to collapse. Hence, it is critical to study the seismic responses ...
Evaluating the Seismic Behavior of Segmental Unbounded Posttensioned Concrete Bridge Piers Using Factorial Analysis
Publisher: American Society of Civil Engineers
Finite-Element Simulation of Posttensioned Steel Connections with Bolted Angles under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: Steel beam-column connections with posttensioned (PT) elements are proven systems that can provide adequate stiffness, strength, and ductility, while eliminating permanent deformations in a moment-resisting frame subjected ...
Finite-Element Simulation of Posttensioned Steel Connections with Bolted Angles under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: Steel beam-column connections with posttensioned (PT) elements are proven systems that can provide adequate stiffness, strength, and ductility, while eliminating permanent deformations in a moment-resisting frame subjected ...
Comparative Seismic Fragility Assessment of an Existing Isolated Continuous Bridge Retrofitted with Different Energy Dissipation Devices
Publisher: American Society of Civil Engineers
Abstract: Seismic isolation is a commonly adopted approach for designing bridges against earthquakes. However, the period elongation in an isolated bridge will generally lead to a large superstructure displacement, which may result ...
Lateral Load–Drift Response and Limit States of Posttensioned Steel Beam-Column Connections: Parametric Study
Publisher: American Society of Civil Engineers
Abstract: The objective of this study is to identify the significant parameters that influence the lateral load–drift response of steel posttensioned (PT) connections. In particular, the effects of variations in beam section size ...
Mechanical and Freeze-Thaw Durability Properties of Recycled Aggregate Concrete Made with Recycled Coarse Aggregate
Publisher: American Society of Civil Engineers
Abstract: The influence of recycled coarse aggregates (RCAs) on the fresh, hardened, and freeze-thaw durability properties of recycled aggregate concrete (RAC) is investigated in the research reported in this paper. Four different ...
