The Experimental Study Of T Shape Reinforced Concrete Beam With Opening Hole

In tall building construction, there is a trend towards providing openings through the web of reinforced concrete beams to accommodate utility ducts and pipes. This can remarkably reduce the building store height, increases the building useable area, and effective reduce the building the construction cost and the usemaintenance cost, so it has the good comprehensive economic efficiency. Compares with the present commonly used structural style, beams with openings have some important advantage, such as better performance under load, less building material and construction expenses, etc. So there is cheerful prospect for the application of beams with openings.This article mainly discusses the character of behavior of reinforced concrete beams with opening hole which reinforcing steel bar is not set around.This paper firstly make an introduction of the reseach and application of reinforced concrete beams with openings , then analyzes and discusses loading capacity ,deflection and sacks of the beams, etc.Base on the past reseach,and according to this test result, the character of behavior and the diferent patters of failure of the beams are summarized.
