In this paper, a three dimensional analysis is performed to investigate the static instability of long-span cable-stayed bridges due to wind loading. Cables made of carbon fiber composite cable (CFCC) are studied. Nonlinearity due to displacement-dependent wind loading is considered. A 1400meter cable-stayed bridge model is used to investigate the static behavior of bridges with both steel and ...

Although much effort has been devoted in the last decade to solve the problem of synthesizing the frequency dependent transformation matrix in unbalanced multiphase cable system, we believe the best solution is to completely eliminate the necessity of the frequency dependent transformation matrix. This paper presents advances in the development of a new cable model (zCable) which splits the rep...

Aim: To investigate the prevalence of four major dental traits in the southern Chinese permanent dentition and to compare these with studies from different populations. Materials and Methods: The material used in the study consisted of high quality study models collected from 725 randomly selected 12-year-old children in Hong Kong (358 males and 367 females). The various traits were assessed us...

INTRODUCTION Collecting clinical data has huge benefits, and many bespoke systems have been well supported by clinicians with outputs leading to improved care. The National Health Service (NHS) has one of the most comprehensive data collection systems for inpatients in the world (Hospital Episode Statistics). Although the data are used extensively for commissioning and NHS management, few clini...

Thank you for making Dr. Moses’ proposal available for public discussion [see Gerald Weissmann (2009) Shovel-Ready Science: Moses Applies for a GO Grant. FASEB J. 23: 2337–2340]. After reading this proposal, I am deeply concerned over his failure to acknowledge any of the research done by my team. Our work is based extensively on that of Dr. Moses’ important early studies, and we have achieved ...

Inclined cables are essential structural elements that are used most prominently in cable stayed bridges. When the bridge deck oscillates due to an external force, such as passing traffic, cable vibrations can arise not only in the plane of excitation but also in the perpendicular plane. This undesirable phenomenon can be modelled as an auto-parametric resonance between the in-plane and out-of-...

We evaluated the potential of a fiber optic cable connected to distributed temperature sensing (DTS) technology to withstand wildland fire conditions and quantify fire behavior parameters. We used a custom-made 'fire cable' consisting of three optical fibers coated with three different materials-acrylate, copper and polyimide. The 150-m cable was deployed in grasslands and burned in three presc...

Cable-stayed bridges are one of the most popular types of long-span bridges. The structural behaviour of cable-stayed bridges is sensitive to the load distribution between the girder, pylons, and cables. The determination of pretensioning cable stresses is critical in the cable-stayed bridge design procedure. By finding the optimum stresses in cables, the load and moment distribution of the bri...
