stainless steel 'T' Section design
stainless steel 'T' Section design
(OP)
G'day guys
I am designing a 'T' section which is make of stainless steel grade 316 (316 L).
Currently I am referring to AS 4673 section 2 for checking all the bending shearing and deflection. However, I am not very familiar with the code and there are some terms which I could not fully understand . For example, what is the difference between effective section modulus and elastic modulus? can I just assume for the full cross section modulus?
Also I read other threads, seems some people refer to another book, AISC stainless steel. I don't have access to the book, just want to make sure is this the definite book i need to look into? I prefer AS standard, wondering if anyone is familiar 'AS 4673 cold form stainless steel'
appreciate if anyone can give me some lead, thanks

RE: stainless steel 'T' Section design
Elastic modulus is a property of the material and is also known as Young's Modulus or Modulus of Elasticity and is defined by stress divided by strain. For most steels, it is in the order of 29,000,000psi or about 200,000MPa.

typo mistake i have made. I meant elastic section modulus and effective section modulus, both of which are being mentioned in AS 4673.
I understand the concept of section modulus and young's modulus, thanks

In the case of light gauge sections, elements in compression may have an "effective" width which is less than the actual width to compensate for the fact that they may buckle under stress. I don't know the AS 4673 code but the Canadian code defines the effective width of various elements which, together, form the effective section. The effective section modulus is the section modulus of the effective section and is always less than or equal to the elastic section modulus.

I must have beaten you by seconds!

Yup, looks like it!
