How Stresses are Transferred from R.C. Columns to Footings?

Madeh Izat Hamakareem — Sun, 28 Apr 2019 18:32:49 +0000

A proper understanding of the transfer of stresses(generated due to applied loads) from columns to the footings or piles is crucial for the design of sound footings. Factored forces and moments at the base of columns are transferred to the supporting foundations by bearing on concrete and by the extension of longitudinal reinforcement into the […]

Offset Bent Longitudinal Reinforcement in Columns and its Requirements

Madeh Izat Hamakareem — Wed, 27 Mar 2019 19:31:16 +0000

Offset bent longitudinal reinforcement is the bending of vertical reinforcement bars of a column (larger column) at a particular storey in order to bring the bars within the limit of a column above (smaller column), as illustrated in Fig. 1, A. The maximum slope of the bent bars should be 1 in 6. Added to […]

Measures to Increase Ductility of Reinforced Concrete Structural Members

Madeh Izat Hamakareem — Thu, 08 Mar 2018 17:57:35 +0000

Ductility is the ability of reinforced concrete members to undergo considerable deflection prior to failure. This characteristic of reinforced concrete structural members is crucial as it provides signs of failure and prevents total collapse. This is especially significant in seismic areas. Measures used to enhance ductility performance of reinforced concrete elements are discussed. Fig.1: Reinforced […]

What is a Plinth Beam? Its purpose, Applications and Construction: Explained With Video

Madeh Izat Hamakareem — Sat, 10 Feb 2018 16:37:07 +0000

What is a Plinth Beam and its Purpose in a Building? Plinth beam is a reinforced concrete beam constructed between the wall and its foundation. Plinth beam is provided to prevent the extension or propagation of cracks from the foundation into the wall above when the foundation suffers from settlement. Plinth beams distributes the load […]
