The vortex-induced force of bridges is not synchronized along the span direction. spatial correlation becomes obvious when bridge structure gradually increases, and mass decreases. Therefore, it important to study spanwise forces long-span ensure accuracy prediction vibration response bridges. established improved theory experimental research methods for analysis large-span by discussing during...

In steel trapezoidal box girder bridge systems, the U-shaped steel girder is designed to act compositely with the concrete deck to form a closed box for live loading. During the construction stage, however, the behavior is not well understood. The usual practice of assuming the system to be non-composite during construction requires substantial top flange bracing to form a quasi-closed box sect...

The authors consider the determination of eigenforms a beam on elastic support parts. Elastic parts made rubber and laminated metal plates find wide use for seismic isolation bridges in earthquake-resistant construction. Determination structures is main stage when designing buildings resisting impacts. span structure girder considered as system uniformly distributed load, free vibrations which ...

In order to address the difficulty in determining seismic damage probability of continuous girder bridges under construction, vulnerability analysis method construction state is proposed this study. Firstly, taking a long-span prestressed concrete composite box bridge with corrugated steel webs (OSW) as an example, finite element models (FEMs) dynamic calculation different phases cantilever are...

<p>In 2020/21, the “Chaumény” footbridge was built in posttensioned UHPFRC over a railway line city of Montreux, Switzerland. stands for Ultra High Performance Fiber Reinforced Cementitious composite. shows high resistance both tension and compression as well excellent durability properties. The design construction lightweight structure is described. consists U-shaped trough girder with s...

In this study, the load carrying capacity was evaluated using results of dynamic test, instead static test field, in precision safety diagnosis a high-speed railway PSC BOX girder bridge, and differences impact factor bridge according to condition train configuration were compared. The obtained from measured displacement response via tests for performed on bridges. analysis conditions included ...

Interest in the seakeeping loads of vessels has increased dramatically in recent years. In current design practice, methods for predicting seakeeping motions and loads are mainly in two categories, strip theory methods and 3Dpanel methods. Methods based on strip theory provide reasonable motion prediction and are computationally efficient. However, many strip theory methods provide only hull gi...
