What does this research mean for the field?

Rhombic and groove shape UHPC wet joints exhibit superior cracking resistance compared to rectangular joints, and increasing the reinforcement ratio significantly enhances flexural capacity, whereas the overlapping form and length of longitudinal reinforcement have negligible effects.

Overview

Randomized trial evaluates bending behavior and cracking resistance in UHPC joints, indicating effective design guidelines for precast structures.

Key Points

This research investigates the bending behavior and cracking resistance of UHPC wet joints in multi-girder bridges.
Conducted four-point bending tests on ten bridge panel specimens with UHPC wet joints.
Developed a refined finite element model (FEM) with ABAQUS to simulate bending behavior.
Performed a parametric study on 36 UHPC wet joint specimens evaluating several design factors.
The FEM showed good agreement with experimental data on load-deflection curves and failure modes.
Rhombic and groove shape wet joints demonstrated better cracking behavior than rectangular joints.
Increasing the reinforcement ratio from 1.13% to 1.35% significantly improved the flexural capacity of the joint.
