Environment-Induced Performance of End Concrete Diaphragm in Skewed Semi-Integral Bridges
Buildings, 2022 Past research has shown that as skewed bridges change temperature, additional lateral movement or forces will occur along with the elongation of the bridge. Even though past research has documented this behavior, lateral movements of semi-integral bridge

Structural Concrete, Volume 24, Issue 2, Page 2563-2574, April 2023., 2023 Abstract Deck caps of bridges—in Germany shortly known as “bridge caps”—are usually made of steel reinforced concrete to form the anchoring area for the guardrail of bridge deck edges on existing cantilever slabs. Combined with protective devices, the outside arranged deck caps provide safety against lateral breaking or crashes of vehicles.

Study on Influence of Joint Distribution on Surrounding Rock Failure of an Underground Tunnel
Geofluids, Volume 2021, Issue 1, 2021., 2021 Due to geological structure and artificial disturbance, a large number of joints and fissures are formed in the surrounding rock of an underground tunnel. In order to study the influence of joints on the failure characteristics of tunnels, three test schemes with different joint lengths, joint spacing, and joint positions are designed. The results show
