To effectively control the stress state and spatial alignment of arch ribs in cable hoisting construction a long-span, concrete-filled, steel tube bridge ensure safety structure, it is necessary to calculate determine appropriate force. Based on actual project double-span, tubular bridge, stage left span from beginning closure taken as an example. The linear method “quiet do not move” adopted. ...

An analysis of the effect vehicle loads on fatigue life local arch bridge suspenders in Southwest China was conducted by generating statistics, creating a model, and developing prediction method: First, Midas model an established, random flow simulation Monte Carlo method, stress spectrum calculated. Secondly, ANSYS software used to estimate suspenders, accuracy proposed method verified. Finall...

It is believed that the Yılanlı (or Leylekli) Bridge (bridge with stork or snake figures) in Tokat, a city high seismicity, was built during Roman Byzantine period. Although no structural damage found on bridge, which still open to pedestrian traffic, it very important determine seismic behaviour of bridge considering possible earthquakes structure will be exposed. This article presents respons...

Abstract This research concerns the use of warped ruled surfaces in load bearing structures 19th century stone bridges Prague. The descriptions a skew arch used at Negrelli Viaduct and special surface called “corne de vache” Legion Bridge are based not only on historical survey, archival materials period publications, but also contemporary measurements.

Abstract—It is a major challenge to build a bridge superstructure that has long-term durability and low maintenance requirements. A solution to this challenge may be to use new materials or to implement new structural systems. Fiber Reinforced Polymer (FRP) composites have continued to play an important role in solving some of persistent problems in infrastructure applications because of its hi...

The foot is constituted from a series of small bones making a segmented structure with multiple joints, likened to a dome, in contact with the ground in three points: posteriorly the calcanear tuberosity; anteriorly and medially the head of 1st metatarsum, and anteriorly and laterally the head of 5th metatarsum. In fact, each foot presents a semi-arch whose base is represented by the lateral bo...

In a half-through steel arched bridge, the suspenders are critical load transfer component that transmits deck system and traffic to arch rib. These subjected environmental vibrations prone fatigue failure, especially for overloaded moving vehicles. This paper aims study impact of vehicles’ rate on performance in long-span three truss bridge. Based Mingzhu Bay 3D finite element bridge model was...

Purpose: There are many bridges being constructed in Nepal. Brides of different types like Bailey truss, cable stayed, RCC Arch, pre-stressed, Slab, T-Beam, Steel Box, Stone masonry arch, suspension, and suspended tendered at present Most the T-beam Prestressed bridges. It has been found need to carry out research develop logical price adjustment coefficient ranges for contracts make provision ...

Research evolution regarding dental research determines the increase of patient's desire to preserve their dentition for a long time. The loss of a molar tooth as the last teeth present on the dental arch, raises issues regarding how the prosthesis should be placed, still patients are usually reluctant to use as last resort the prosthetic solution. This article describes the technique of root a...
