Used in lighter constructions, such as decks, fences, and temporary structures 7 Design Often elaborate with classical elements like bases, shafts, and capitals Generally simpler, focusing on functionality 6 Material Commonly made of steel, concrete, or stone for strength and stability Can be made ...
A numerical algorithm for predicting the moment capacities of circular CFT, with or without the post-tensioning effects, has been validated against the test results by the authors as well as those published in the literature. 展开 关键词: Concrete-filled steel tubes Ultimate moment capacity ...
In the case of horizontally curved highway bridges, girders are subjected to the combined action of vertical bending and torsion due to the offset. Althoug... K Kim,HY Chai - 《Advances in Structural Engineering》 被引量: 20发表: 2006年 A Study of Pretensioned High Strength Concrete Girders...
When computing the pre-stress loss of the post-tensioning pre-stressed concrete component caused by the anchorage device deformation,we have to use the trial balance procedure to calculate the pre-stress loss.To resolve this complicated trial problem,this article deduced a new way to compute the ...

This paper presents a theoretical study on the post-local buckling behaviour of steel plates in welded steel box columns filled with concrete, by using the finite element method. The effects of various geometric imperfections, residual stresses and width-to-thickness ratios on the post-local bucklin...
Using a large amount of construction waste,which was generated by Wenchuan earthquake,to produce recycled concrete blocks,is an important approach to utilize construction waste as resources.Based on the application of recycled concrete blocks in the earthquake hit-area,for reconstruction of villages and...
Larger structural concrete members may also be post-tensioned, especially in bridges and floors and beams in parking structures. The process is very similar to that used for slabs, except on a bigger scale. One interesting difference is that the tendons will often be "draped" so that they are...
