A new reinforced concrete beam [PDF]

WIT Transactions on The Built Environment, 2012
The introduction of high strength concrete and steel reduces the size of structural members whilst having the same load carrying capacity and a resultant saving on construction time, material, labour and space. Therefore, using both high strength steel and high strength concrete in construction is very important for producing a lightweight structure ...

Reducing the shear reinforcement in reinforced concrete beams and slabs

Magazine of Concrete Research, 1965
Summary The shear tests reported in the present paper were carried out in Stuttgart from 1961 to 1963. The mechanism of failure at ultimate shear load is explained in terms of the truss analogy, and the ratio between the width of the compression flange and the thickness of the web is shown to have a considerable influence on the inclination of the ...

Rehabilitation of Reinforced Concrete Beams

Tikrit Journal of Engineering Sciences, 2017
The concrete structures are often exposed to damage as a result of several factors including, environment, design, and other factors, and because of the high cost and long time needed for reconstruction of the damaged buildings, it become necessary to consider methods for rehabilitation of the damaged structural member in the building.

Flexural Test of Fly Ash based Geopolimer Concrete Beams

MATEC Web of Conferences, 2017
Fly ash is a by-product from the coal industry, which is widely available in Indonesia. Fly ash contains quite high silicate and alumina. Silica and alumina reacts with alkaline solution to produce alumina silicate gel which binds the aggregate to ...

Calculation of Cracks in Partially Steel Fiber Reinforced Concrete Beams with BFRP Bars

Advances in Materials Science and Engineering, 2022
The effects of steel fiber volume rate and steel fiber concrete thickness on the crack development and crack resistance of basalt fiber reinforced polymer (BFRP) beams were investigated by flexural tests on six partially reinforced BFRP steel fiber ...
