Nonlinear Stiffness of Semi-Fixed Dowel Joints in Semi-Integral Bridges
The semi-fixed dowel joint studied in this paper consists of a steel dowel with rubber sleeves and a rubber pad to connect the superstructure and the substructure and to support the main beam. This type of joint is suitably used in retrofitting a jointed

An investigation on the effect of cyclic displacement on the integral bridge abutment
The integral bridge abutment, as a special type of retaining wall, is subject to cyclic displacement, which is due to the daily and seasonal temperature variations. The frame of this type of bridges is rigid and jointless.

Reliable joint connection is key to designing prefabricated structures. To study the mechanical properties of the vertical joints in the designed prefabricated underground silo steel plate concrete composite wall and verify their reliability, flexural and compressive experiments were conducted using two groups of six full‐scale steel plate concrete ...

Pier settlement is unavoidable in the construction and operation of high‐speed railways. This paper presents a work on the influence of pier settlement on additional structural stress of longitudinal connected track (LCT). First of all, the generation mechanism of additional structural stress of LCT caused by pier settlement is described in detail.

Numerical investigation on primary and secondary cracks in thick concrete members
Abstract This study investigates the crack formation process in thick reinforced concrete members subjected to imposed deformations, focusing on the development of secondary cracks in addition to geometrically set primary cracks. A validated nonlinear fracture‐plastic finite element model is used to analyze the influence of reinforcement layout, member
