2.5 CONCRETE MIX DESIGN AND REDESIGN . 2.5.1 Mix design 2.5.2 Mix re-design 2.5.3 Self-Compacting Concrete. Concrete Batching Plants. Moisture control in aggregates. Normal Distribution. mean = failure level + z  standard deviation. Percentage failure permitted. z value. 16. 1.00.

Welcome Back. EA 2 January 2011. Common Truss Designs. Bridge Building. Design Requirements. Needs to span 24 meters Needs to be .4 meters wide Needs to be designed for a “traffic load” of 240 kg Your factor of safety needs to be 2.0 Bridge made of standard manila folders

Second Order Analysis . In the previous classes we looked at a method that determines the load corresponding to a state of bifurcation equilibrium of a perfect frame by eigenvalye analysis The system was assumed to be perfect, and there were no lateral deflection until the load reached P cr .
