Chapter 2 - Analysis of Statically Determinate Structures

Objectives Identify common support connections. Identify/draw idealized structures. Calculate tributary loadings. Judge between one-way or two-way system. Determine beam/joist's distributed load from appropriate tributary area. Determine girder loads. Determine column loads. Judge whether a structure is stable/unstable. Judge whether a structure is statically determinate/indeterminate. If indeterminate, specify degree of indeterminacy. Calculate a structure's support reactions. Identify any two-force members. Draw free-body diagram(s). Derive summation-of-forces and summation-of-moments equations. Apply algebra to solve for requested values.
