I'm a student so am still learning, anyway I think I know what a continuous beam is: a beam that spans more than two supports. I have a project to design a building however going through lecture notes for preliminary design I have come across this:
'Based on the practice of experienced designers a number of “rules of thumb” have been suggested to propose the initial size of members. For instance some designers use the following “rules of thumb” for the preliminary sizing of RC beams:
for simply supported beams: h>=L/16
for beams with one end continuous: h>=L/18.5
for beams with both ends continuous: h>=L/21
for cantilever beams: h>=L/8
where h= height of the beam, L= length of span'
Now I can't seem to find anything anywhere else that differs between continuous beams, and nor can I think what it might mean. I feel stupid asking this but no one seems to know and my lecturer has been ignoring me :/ I possibly thought he may not mean a continuous beam as such but be referring to an overhang but given that the building I am designing is a general grid layout I don't think anything is overhanging so am just a bit puzzled. Any help would be greatly appreciated :)

Hi. Just a quick request. Could somebody tell me the minimal length of cantilever beam (in relation to the dimensions of the cross-section). Additionally I'd need a reference... - I need if for my thesis and cannot find a source. Thanks in advance!!

Dear, Good Day, We built a house in 1992 without finishing, there are many cracks appear on the wall after some year. I plan to do complete the house but unable to take any decision on the crack. Appreciate for your assistant to complete the house with your great advice. Please revert back, I will forward the snap shots.
Thanks & Regards, Fazl

I know there are differences between soffit and back arch. Can anyone explain this to me?
What is R.C.C (Reinforced Cement Concrete) Lintel? Why these RCC lintels are popular and used widely?
My inyinirs, i show you my project for a government complex. I only need to fill the area which is inside, and my guests say that the central building of that place must be triangular. The problem for me is that it's not easy to locate in a central place because the triangulation, which triangulation system do you recommend me?. I have been talking with Calatrava's office but they say that the best solution is a curve structure.....but my guests want it triangular. What can i do, my friends?. The time is running for me. I show you the planning in here. Here is the photo... https://www.facebook.com/photo.php?fbid=10202058420836813&set=gm.10152263787995645&type=1&theater
