background: dose calculation algorithms play a very important role in predicting the explicit dose distribution. we evaluated the percent depth dose (pdd), lateral depth dose profile, and surface dose volume histogram in inhomogeneous media using calculation algorithms and inhomogeneity correction methods. materials and methods: the homogeneous and inhomogeneous virtual slab phantoms used in th...

The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...

Because of their beautiful appearance, strong crossing ability, and reasonable stress performance, the application tied steel box arch bridges is becoming more extensive. Bridge construction monitoring can control adjust deviation state to ensure linear bridge after completion. This study carried out a symmetrical analysis completed evaluation newly built Dafeng River in Guangxi Province based ...

The bridge tower beams of long-span bridges freeze during winter. accumulated ice on the beam flakes off and falls into deck from a high altitude with temperature rise, threatening traffic safety. To solve this problem, an electric heating method is used to melt snow beams. A design scheme based embedding carbon fiber wires in proposed which electrical energy converted heat beam. In paper, icin...

After 1994, highway bridges are maintained under the Special Law on Structure Safety in Korea. To keep a structure good condition, inspection of the structure has to be performed periodically. The inspection is hard work and needs a lot of time and many inspectors to inspect the structure that is important or damaged. Generally, This contains subjectivity of inspector, and so the result of insp...

Steel-concrete composite slabs with cold-formed, profiled steel deck sheets are popularly used in steel-framed buildings. In these slabs, the platform acts as a working during construction and also tensile reinforcement under in-service load conditions. The shear bond capacity of slab is evaluated this study for two different profile sheets. Specifically, their behaviour investigated by casting...

The concept of robust reliability is de®ned to take into account uncertainties from structural modeling in addition to the uncertain excitation that a structure will experience during its lifetime. A Bayesian probabilistic methodology for system identi®cation is integrated with probabilistic structural analysis tools for the purpose of updating the assessment of the robust reliability based on ...
