Mount mechanisms for the Saturn 5/Apollo mobile launcher at John F. Kennedy Space Center [PDF]

open access: yes, 1975
A support system was designed to resist hurricane wind loads at the launch pad and to allow the supported structural frame to expand and contract freely under wide ranges of temperature.

The Effect and Mechanical Mechanism of Intermediate Diaphragms in Prefabricated T‐Beam Bridges

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Current bridge design codes stipulate that prefabricated T‐beam bridges must include intermediate diaphragms, with spacing not exceeding 10 m. However, the construction of these diaphragms entails extensive overhead work, elevated safety risks, and significant challenges in quality control.

Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Currently, bridge load tests use the verification coefficient to evaluate the structural performance of bridges in China, but this method is unsuitable. This paper presents a method that utilizes reliability to compare the actual bridge structural performance with the designed performance. Reliability functions for strain and deflection in load testing

Charles Marcellis and Arthur Vierendeel: a century of Belgian bridge building (1835-1940) [PDF]

open access: yes, 2012
The Belgian bridge builders Charles Marcellis (1798-1864) and Arthur Vierendeel (1852-1940) were jack-of-all-trades in the 19th century, but both were mostly known as bridge designers, trying to have a grip on new structural possibilities.

Study on Mechanical Behavior of Longitudinal Wet Joints of Prefabricated Assembled Beam

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigates the impact of various interface construction techniques on the bending strength of longitudinal wet joints in bridge superstructures through experimentation. A functional relationship between measured bending strength and theoretical shear strength values is established by finite element simulation.
