Spanning beams the reinforcement is primarily located in the bottom half of a section and at the midspan.
The reinforcement is generally located to compensate for the concrete being weak in tension e.g in Reinforcement links are often mild steel ( f y >= 250 N/m 2 ) although high yield steel is becoming more popular.įor reinforced concrete slabs and walls it is convention to use mesh reinforcement. The main reinforcement bars are generally high yield deformed bars ( f y >= 460 N/m 2 ). The concrete reinforcement is generally steel although other materials are sometimes used The strength of the resulting mixes is generally confirmed by a cube crushing test. Much of the mixing is now done off site by ready mix companies The strength and durability of the resulting concrete depends on the quality and quantity of each of the constituents and onĪny additional additives have been added to the wet mix. Information on concrete forms is provided on webpage concrete. Physical changes to occur that result in a hard and durable material. These are mixed together in a homogeneous mass and are then put in place and left for the chemical and The concrete composition is an based on three constituents : aggregate, cement and water. It is composed of two distinct materialsĬoncrete and reinforcement, each of which can be varied in quality disposition and quantity to fulfill a wide range of construction Reinforced concrete is probably the most prolific and versatile construction material. Must be completed in accordance with the relevant codes. Latest codes they are simply provided to enable mechanical engineers to understand the topic and produce basic design studies. The notes are not intended to enable detail design to the The symbols are generally different (N in BS8110 = N ED in BS EN 1992).
There are a number of differences between BS 8110 and BS EN 1992 e.g This standard has now been replaced by Eurocode BS EN1992. It is important to note that I have based most of the content of this page on BS 8110 -1:1997.
This page includes some notes on reinforced concrete as used in the construction of wallsĪnd structures. They are very much work-in-progress and I will be updating them on a regular basis over the next six months. The building structures pages have been added over the six months to Dec. It is also possible to become a BSI member and obtain copies of
