What are rebar use for?
Rebar locators are used to find exactly where the reinforcing steel is located under concrete in existing materials. They are most often used for renovation or remodeling projects.
Difference between T-beam and rectangular beam?
Dasign of T- beam is some what similar to rectangular beam, in design slab thickness is determined first. the slab is acts as compression flange in designing the beam. the flange acts as compression zone, which is balance by steel embeded in the bottom web of the beam. slab thickness= t, in. effective depth= d, in. width of web= b', in. flange width= b, in. width of flange should be least of the three alternatives, 1. span/4. 2. b' + 16t. 3. centre to centre spacing of beams.
What is the difference between built-up steel sections and rolled steel sections?
Built up steel sections are comprised of other smaller members. This could be 3 plates welded together to form an I-shape or 2 angles bolted back to back to make a double angle shape. Compare this to rolled sections, which are formed (called rolled) into the shape directly. Therefore, it was one whole member, as if you were pushing play dough through a form. The issue one must consider with built-up shapes is that the welding or punching for bolt holes creates a significant residual stresses in the member, weakening its capacity. While rolled sections do still contain residual stresses from uneven cooling (flanges and web cool at different rates because of heat/mass transfer), the residual stress in a rolled shape is much less than that of its built up member counterpart.

What is the fire rating of concrete?
12" is a good rule of thumb for 2-hour rating....but the 2006 IBC will give you a more accurate indication, plus industry web sites for concrete vendors will give you more accurate info.....
What is the different between local buckling and lateral buckling?
Main difference between local and overall buckling related to distortion of the overall system geometry. Local buckling does not cause distortion of the overall geometry, usually local buckling seems on short (channel or angle) compression members (excessive loaded and material related problem). On the other hand overall buckling causes distortion, we can give example as plastic ruler compressed by fingers . There is equation on buckling developed by Euler.
What size open web steel joist be used to span 20 feet with dead load of 20psf and live load of 40 psf?
A DLH will work.
How much of a gap is left between each end of the floor joist and the web of the rim joist to prevent squeaking?
No gap is intentionaly left. Your squeaking will be between the subfloor and joists.
