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

To effectively prevent the buckling-restrained braced reinforced concrete (BRB-RC) frame substructure from shear or flexural-shear failure caused by frame action prior to the BRB, a controllable failure mode design method based on a novel sliding gusset connection was proposed. The method addresses problems of the current siding gusset connection, such as the limited bearing capacity of the anchorage plate and the unreasonable design of the shear capacity of substructure beams. Quasi-static tests were conducted on five full-scale BRB-RC subassemblages, one with a traditional connection and

This paper conducted an experimental study on seismic performance of weld box-shaped columns made of Q345FR and Q460FR fire-resistant steels to enhance the application of fire-resistant steel structure in seismic regions. Through a validated numerical model, a parametric study was subsequently performed to clarify the influence of axial load ratio, slenderness and plate width-to-thickness ratio on the seismic behavior. The fire-resistant steels demonstrate an obvious cyclic-softening behavior. Columns with cross-section of ‘Level 1’ in GB 50011—2010 exhibit a failure mode
