Chapter 2 Design for Shear - Engineering
by.genie.uottawa.caThe nominal strength of a rectangular section is the sum of concrete strength Vc and reinforcement strength V s to give V n = K fc K vc + K vs ( A v /s ). SHEAR 3 is a design aid for use if Grade 60 stirrups larger than #5 are to be used, and sections must be
Fire and Concrete Structures - Portland Cement Association
www.cement.orgConcrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance.
IS 1786 (2008): High strength deformed steel bars and ...
law.resource.orgstrength. High strength deformed bars and wires for concrete reinforcement are being produced in the country for many years by cold twisting and by controlled cooling and micro-alloying. A brief note on controlled cooling process is given in Annex A for information only. In the past few years there has been increasing demand for higher strength
