Plaster ceilings

To relieve shrinkage, temperature or stresses, plaster ceilings should have control joints within regular spacings. What is the minimum recommended spacing (ft) in each direction and the maximum area (sf) between control joints in plaster ceilings? Answer At least every 30 feet and a maximum of 900 sf between joints. ARE 4.0 exam prep: BDCS

Allowable stress

Identify this code requirement for allowable stress in steel, where F ? = 0.60F y (Choose 2) A. For tension on the gross area B. For shear on gross sections C. Where a beam is not a compact section but supported laterally, for bending D. For tension on the net effective area E.

ARE 4.0 guidelines

An easily overlooked bit of information is on page 22 of the most recent ARE 4.0 Guidelines (July 2011 pdf available from this page ). NCARB advises that in addition to ICC/ANSI A117.1-98 accessibility standards, candidates should be familiar with the following for EACH division: ICC 2006  International Building Code, International Mechanical Code, International Plumbing Code NFPA Life Safety Code NFPA101, National Electrical Code NFPA 70 NRC Canada National Building Code of Canada, National Plumbing Code of Canada, National Fire Code of Canada AIA AIA Documents 2007 One may infer that each division can test from any of these codes and documents.  Ever wonder why you might face a question that seems really off-topic for the exam title and description?  Perhaps this is why.
