Experimental Determination of Dynamic Allowance for Traffic Loading in Bridges
Bridge codes adopt values for dynamic allowance in traffic load models that are necessarily conservative to cover for an entire range of bridges with different mechanical characteristics, boundary conditions, and the large number of uncertainties associated to the vehicle-bridge interaction problem. A further level of conservatism occurs due to the independent manner in which the governing stat...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولSensitivity of Overpass Bridges to Wind and Traffic Loading
bridges are planned for construction on the U.S. 59 in Houston, Texas. Each bridge will be of the tied-arch type and will be constructed on-grade over cut areas with clear spans of 228 f t (69.5m). To expedite construction, unique procedures are planned which use existing bridges as platforms for final fabrication of the tied arches. This procedure requires consideration of wind loadings on the...
متن کاملRecent Innovation for Concrete Highway Bridges
A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...
متن کاملLive load model for highway bridges *
Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...
