Plastic Hinge Model for Performance-Based Design of Beam-Column Joints
Publisher: ASCE
Abstract: For performance-based design of reinforced concrete moment frames, the inelastic load-displacement relationship including strength degradation of beam-column joints should be accurately defined. In this study, a simplified ...
Eccentric-Axial-Load Test for Composite Columns Using Bolt-Connected Steel Angles
Publisher: ASCE
Abstract: For better structural performance and constructability, a concrete-encased steel column that uses a steel cage prefabricated with bolt connections was developed. The steel cage consists of longitudinal steel angles and ...
Behavior of High-Strength and Ultrahigh-Performance Concrete Targets Subjected to Relatively Rigid Projectile Impact
Publisher: ASCE
Abstract: This experimental study was conducted to evaluate the impact behavior of relatively rigid projectiles with conical and hemispherical nose shapes on normal to high-strength and ultrahigh performance concrete (UHPC). For ...
Axial Compressive Behavior of Predamaged Concrete Cylinders Retrofitted with CFRP Grid-Reinforced ECC
Publisher: ASCE
Abstract: A fiber-reinforced polymer grid-reinforced engineered cementitious composite (FRPECC) is a promising strengthening composite that addresses the drawbacks of FRP and textile-reinforced mortar (TRM). The present study focused ...
Monotonic and Cyclic Axial Compressive Properties and Modeling of Basalt FRP-Retrofitted Predamaged Short Columns
Publisher: ASCE
Abstract: This study investigated the monotonic and cyclic axial compressive properties of predamaged concrete retrofitted using externally bonded basalt fiber-reinforced polymer (BFRP) sheets. Plain concrete cylindrical specimens ...
Punching Shear Strength of Post-Tensioned Transfer Slab-Column Connections
Publisher: ASCE
Abstract: Current design codes specify the need for two-way shear strength analysis for prestressed slab-to-column connections. This paper is an investigative study of said interaction for post-tensioned (PT) transfer slabs. Two-way ...
Flexure-Shear Capacity of Perforated Steel Beams Reinforced with Novel Ring Plates
Publisher: ASCE
Abstract: A web opening at the end zone of an I-section steel beam decreases the load-carrying capacity of the steel member. In the present study, a reinforcement method for circular web opening was investigated, applying novel ...
Static Load Test on the Progressive Collapse Resistance of Precast Concrete Frame Substructure during and after High Temperature
Publisher: ASCE
Abstract: With the recent increased use of precast concrete (PC) structures, their progressive collapse resistance under hazardous conditions, such as explosion and fire, has become a great concern for the structural engineering ...
Behavior of Hollow Structural Section Branch-to-Casting Node Connections for Free-Form Grid Shell Structures
Publisher: ASCE
Abstract: Casting nodes are used to connect branch members at joints of freeform grid shell structures. In this study, the structural performance of a rectangular hollow section (RHS) branch-to-casting node connection was investigated. ...
Device for Load-Redistribution between Existing Piles and Underpinning Micropiles
Publisher: American Society of Civil Engineers
Abstract: A micropile preloading method using bolt-fastening was studied to improve the constructability and economic feasibility of underpinning micropiles for the vertical expansion of a building with existing pile foundation. Due ...
