Can anyone explain to me in simple terms what flexure is, i.e. in the context of structural design.

Many thanks

Flexure is in essence beding of an element which induces compression and tensile stresses at a maximum at the outer fibres. I suggest you get your hands on a basic stuctural mechanics book.

Sorry that should read 'bending' of an element not beding!

I don't think a structural definition is any different from a layman's definition.  Flexure is bending.

When you load a beam it bends/ flexes.  Maybe you could say rotational deflection?  We could make rotation more complicated by saying things like the differential of the deflection or the integral of the moment.

You might want to give us some more context.

Interestingly Marblaze has made 6 postings but never made a single response.

They talked about research on previous posts so I think they are a student.

I am a part time student and working full time.

thanks for your help.

just out of curiosity - what do you do for work right now and what are you studying (undergrad or grad)?

Law ?  Accountancy ?

I work at HOP in Brighton UK,

I am currently taking up MSc Civil Engineering in Brighton University.

what is your undergrad degree in?  I have a hard time imagining how you can be in a MS CIVIL program and not understand what flexure is.

I certainly meant no disrespect with my last post.  I am pretty certain that all civil undergrads need, at a minimum, a structural analysis and/or a design course for some material (be it steel or concrete), and getting through that without understanding flexure is very surprising to me.  Again, no disrespect intended.

Take a 2x4 or other piece of lumber about 3 meters long and support with bricks at each end.  Step on it.  It deflects.  It FLEXS.  That is flexure or bending.

well my undergrad is bs civil engineering, it's just that my first language is not english.

i don't much problem when it comes to solving structural problem. but when i start writing my thesis and reading the british standard and eurocode, some words just don't make sense to me.

another classic example is 'decompression' in the contexto prestressing. can you help?
