Approval of Special Construction
Increasing use of specialized types of construction not covered by building codes has stimulated preparation of special-use permits or approvals. Model
ANALYTICAL MODELS
An analytical model is a simplified representation, or an ideal, of a real structure for the purpose of analysis. The
Annealing and Normalizing
Structural steels may be annealed to relieve stresses induced by cold or hot working. Sometimes, also, annealing is used to soften
