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 ...
