Truss Model Example
The experiment resulted in diagonal crushing of the concrete at a drift ratio of 0.85%; the analytical model computed the crushing of the diagonal concrete at 0.7% drift in Diagonal E1 [shown in Figure 1(b)]. Figure 3(b) shows the stress-strain history of Diagonal E1, showing the compression strength reduction due to normal tension strain.
