Document Summary
Strucutral engineering design may be thought of as a 5-step process. Note: the ones that were identified in the problem design. Note: reliably indicating that it"s addressing the uncertainty ( ) of both the loads and the material strength. In this course it is assumed that the role of structural engineer is to: Bigger cross-section = able to hold more force. A key element of structural design is the consideration of uncertainty of both applied loads and material properties. Limit states are limiting conditions at which a structure ceases to fulfill an intended function. Mark the onset of serviceability failiures of a structure. Mark the onset of unstable crack growth caused by a spectrum of stress ranges. Mark the onset of collapse of all or part of a structure including: Ultimate limit states are checked at factored load levels . The general form of the limit states design equation at ultimate limit states is:
