14 Deck inclination and vertical displacements are among the most important technical parameters to 15 evaluate the health status of a bridge and to verify its bearing capacity. Several methods, both 16 conventional and innovative, are used for structural rotations and displacement monitoring; no 17 one of these does allow, at the same time, precision, automation, static and dynamic monitoring ...

This paper proposes a curved link-slab (CLS) structure, simplified into hingeless arch model, to address the current cracking phenomenon of CLS concrete. The stress formula under various loads is derived based on classical mechanic’s method. Based an actual bridge example, mechanical properties are analyzed different and load combinations. results show that: (1) significantly lower than that fl...

in general, the aerodynamic stability of long span bridges is evaluated based on the results of wind tunnel tests in the low reynolds number region, because in almost all wind tunnel tests, it is impracticable to satisfy reynolds number similitude. therefore, in order to correctly evaluate conventional wind tunnel test results, reynolds number effects on the aerodynamic force coefficients acting o...

Based on a symmetrical cable-stayed bridge, the wind resistance performance of proposed π-type composite beam is analyzed, and influence changing bridge deck cross slope ratio static dynamic characteristics emphatically studied. The purpose to provide design reference for preliminary study bridge. CFD (Computational Fluid Dynamics) numerical calculation method used solve vibration problem wind-...

Bridge management officials have expressed a keen interest in the use of low-cost and easy-to-install wireless sensors to record bridge responses during short-term load testing. To illustrate the suitability of wireless sensors for short-term monitoring of highway bridges, a wireless monitoring system is installed upon the Grove Street Bridge to monitor structural responses during static and dy...

Improved stream crossings are needed to reduce construction and maintenance costs and reduce the environmental impacts from low-volume forest roads and skid trails. New designs of timber bridges are cost-effective alternatives for portable stream crossing structures. This paper discusses design criteria for portable timber bridges and presents one design for a portable, longitudinal glued-lamin...

The present paper investigates the effect of limit state selection ~strength versus serviceability! on bridge deck life-cycle costs and thus on optimal repair strategies. Such a comparison may then help determine whether safety or functionality ~or both! are important criteria when optimizing bridge life-cycle performance and costs. The structural element under consideration is a reinforced con...
