ULTIMATE LOAD-BEARING CAPACITY OF REINFORCED CONCRETE SLABS WITH THEIR THICKNESS PARTLY INCREASED

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...

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 ...

Punching shear capacity of reinforced concrete slabs with headed shear studs

Ultimate Bearing Capacity of Eccentrically Loaded Strip Foundation on Sand Reinforced with Geogrids

This paper reports the results of model loading tests performed on an eccentrically loaded strip foundation supported by multi-layered geogrid-reinforced sand. Only one type of geogrid and sand at one relative density of compaction were considered. Based on the present laboratory test results, an empirical relationship for the reduction factor has been developed. This relationship can be used t...

Shear Capacity of Reinforced Concrete Flat Slabs Made with High-strength Concrete: A Numerical Study of the Effect of Size, Location, and Shape of the Opening (TECHNICAL NOTE)

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...
