Dear sefian,


Please keep in mind that it is not the kind of steel which determines the suitability for earth quake resistance.But the ductility requirements and detailing rules the  requirement for EQ resistance .

There is no structure that can be said to be able to  withstand the force of Nature, the construction industry have undergone major changes to ensure much safer buildings and one such is the reinforcement used for construction. Nowadays TMT is used for RCC, and it have the necessary safety requirements to withstand disasters to avoid major losses. TMT bars such as Fe 415, have been designed to provide the idea of safer homes.That is the best a man can do to withstad natural forces

The process of making a rebar broadly involves two processes viz. Steel-Making (i.e. production of liquid steel from Raw Materials) and Rolling (Thermo-mechanical treatment to produce rebars). Quality control at both these processes ensures ductile and strong rebar. Use of only TMT technology does not ensure ductility. Many manufacturers who make rebars using scrap steel invariably do not confirm to BIS requirements, although they use TMT technology. These manufacturers do not have the necessary know-how and equipments to control the quality during steel-making process. Hence the end result is poor quality rebars at a low cost.

Of course, use of only ductile rebar is not enough. It has to be backed by judicious use of ductile design & detailing standards like IS 13920 and IS 4326.

Not recommended. There are studies which show that normal r ust increases bond with concrete. It is mentioned even in ACI-318.

Painting TMT bars is not necessary in normal conditions because it is Thermo-Mechanically Treated for corrosion resistance.

only epoxy coated bars are anti corrosion resistant.also galvanized bars have been used in middle east,but those bars are costly.hence epoxy coated bars have been used since 30 years.results are also good. satya pal  On Fri, 10 Aug 2018 21:47:06 +0530 "Ashokkumarmodi"  wrote >                   Whether tmt painted with anti rustic paint is good for structure.
