RISShear Strength and Crack Width Control of Concrete Beams with High-Strength Shear Reinforcement
Publisher: ASCE
Abstract: There is a potential to reduce steel tonnage for construction through the use of high-strength steel reinforcement. However, the current version of the ACI 318 code limits the yield strength of reinforcement that could be ...
Cyclic Behavior of Reinforced Concrete Beams with Corroded Transverse Steel Reinforcement
Publisher: American Society of Civil Engineers
Abstract: This study examined the seismic performance of reinforced concrete beams with corrosion only induced in the transverse steel reinforcement by using cyclic loading. The beams were designed with closely spaced steel hoops ...
Shear Strength Model for Reinforced Concrete Bridge Columns with Multispiral Transverse Reinforcement
Publisher: ASCE
Abstract: A shear strength model is proposed for reinforced concrete bridge columns with multispiral transverse reinforcement. The proposed model consists of a proposed discrete computational shear strength model for multispiral ...
Minimum Shear Reinforcement for Columns with High-Strength Reinforcement and Concrete
Publisher: ASCE
Abstract: Large-scale reinforced concrete columns with high-strength reinforcement and concrete were tested. The nominal compressive strength of concrete was 70 MPa. The nominal yield strengths of longitudinal and shear ...
Cyclic Behavior of Reinforced Concrete Columns with Unstressed Steel Strands as Longitudinal Reinforcement
Publisher: ASCE
Abstract: The use of unstressed Grade 1860 MPa seven-wire steel strands as longitudinal reinforcement has the potential to reduce steel congestion in reinforced concrete members. However, no studies which use unstressed steel ...
Seismic Performance of Reinforced Concrete Beams with Proposed Lap-Spliced Intermediate Hoops
Publisher: ASCE
Abstract: Two types of lap-spliced intermediate hoops were proposed to address the construction difficulty encountered for conventional intermediate hoops or stirrups used in the plastic hinge regions of beams of special moment-resisting ...
Hysteretic Modeling of Unbonded Posttensioned Precast Segmental Bridge Columns with Circular Section Based on Cyclic Loading Test
Publisher: American Society of Civil Engineers
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 ...
Seismic Performance of Segmental Precast Unbonded Posttensioned Concrete Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: The seismic performance of segmental precast unbonded posttensioned bridge columns with hollow cross sections is investigated in this paper. Bonded longitudinal mild steel reinforcement crossing the column segment joints ...
Ground Motion Duration Effects on Hysteretic Behavior of Reinforced Concrete Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: This study examined seismic behavior under long-duration ground motion in flexural-dominated reinforced concrete bridge columns designed per modern seismic design codes. Two column specimens with identical design parameters ...
