متن کاملStructural 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 ...
متن کاملShear Strength of Reinforced Web Openings in Steel Beams
The floor beams of steel buildings, cold-formed steel floor joists in particular, often require large web openings, which may affect their shear capacities. A cost effective way to mitigate the detrimental effects of such openings is to weld/fasten reinforcements. A difficulty associated with an experimental investigation to establish suitable reinforcement schemes for openings in shear zone is...
متن کاملSteel Beams with Web Openings
The responsibility of a Structural Engineer lies in not merely designing the structure based on safety and serviceability considerations but he also has to consider the functional requirements based on the use to which the structure is intended. While designing a power plant structure or a multi-storeyed building, the traditional structural steel framing consists of beams and girders with solid...
متن کاملShear Strength of Slender Reinforced Concrete Beams without Web Reinforcement
This paper attempt to predict the shear strength of high strength concrete beam with different shear span of depth ratio without web reinforcement. The large data base available has been clustered and a linear equation analysis has been performed . The prepared models are functions of compressive strength , percentage of flexural reinforcement and depth of beam. The proposed models have been va...
