To address the issue of large rebar dimensions that cannot be covered by a single camera field of view in processing and inspection, a method for measuring the geometric shape (length and angle) of rebar using computer vision technology was proposeed. A partitioned camera measurement system was proposed. The partitioned cameras were utilized to simultaneously capture images and stitch together a panoramic view based on binary encoded ArUco markers. For real-time computing requirements, a lightweight semantic segmentation network, named as ghost-Unet, was proposed to balance the efficiency a

The size effect of the shear capacity of concrete short beams can be effectively weaken by the reasonable arrangement of shear web reinforcement. Shear tests were conducted on eight BFRP-reinforced concrete short beams with cross-sectional heights of 300mm to 1200mm (including four short beams without web reinforcement and four short beams with horizontal and vertical web reinforcement ratios of 0.5%). The development trends of the failure mode, load-deflection curve, and web reinforcement strain with changes in beam section height were analyzed, and the size effect of shear capacity of BFR

The length-diameter ratio has important influences on the bearing behavior of combined grouting bored piles. Based on the field test data of bored piles in the Jinghang Grand Canal Bridge on Ningliang Expressway, the effects of combined grouting, length-diameter ratio and bearing layer on the load transfer characteristics of bored piles were analyzed. On this basis, the calculation method for settlement for combined grouting bored piles based on the load transfer method and spherical permeation grouting theory was established, considering the influences of length-diameter ratio and an enlar

In this paper, direct shear tests were conducted on 22 Z-shaped specimens to analyze the shear performance of the concrete-grout-concrete double interface in the grouted sleeve connection of precast components. The failure modes, shear strength, shear stiffness, and shear-slip curve variations of the shear interface were examined. Several parameters such as interface roughness, reinforcement ratio, fullness of sleeve grouting, and grout layer thickness were considered in the tests. It is shown that the double-interface shear cracks start at the bonding interface, develop along the interface

A composite connection joint for section steel plug-in welding of concrete prefabricated piles was designed to improve the connection performance of concrete prefabricated piles. The shear and flexural experiments of thirteen composite joints and pile bodies of composite reinforcement concrete prefabricated square piles with section side lengths of 300mm, 450mm and 600mm were conducted to compare the shear and flexural bearing capacities, deformation capacity and failure characteristics of the section steel plug-in welding composite joints and pile bodies. The results show that the shear fa
