ULTIMATE STRENGTH OF REINFORCED CONCRETE FLOOR SLABS

Punching shear strength of steel fibre reinforced concrete slabs

The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional methods of strengthening against punching, steel fibre reinforcement has proved to be an effective and viable alternative. The addition of fi...

Behaviour of fibre reinforced concrete slabs

This paper presents a comparison of the properties of concrete slabs when two types of fibres are added. One specimen had no fibres and acted as a control specimen. The remaining four specimens had steel and polypropylene fibres added in the volumetric ratio of 0.5% and 1.0%. The dimensions of the slab specimens were 820×820×80 mm and were supported by four rollers at their edges. A displacemen...

Effect Of Web Reinforcement On Ultimate Strength Of Reinforced Concrete Deep Beam

It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength o...

Structural Consideration in Design of Reinforced Concrete Slabs with Openings

Over 90% of framed structures in Uganda are built from reinforced concrete. Prior to the 1990’s, most buildings had no openings in slabs, yet in city centers buildings butt against each other with widows at front and back only. This limited retail activities to front rooms of the ground floor and the buildings had to be narrow. A baseline survey of 50 shopping malls in Kampala Central Business ...
