Modeling Piles/Piers in FEM Software

When we use finite element software for analyzing deep foundations then it becomes important to model piles with accurate axial stiffness so that the load can distribute properly based on pile stiffnesses. Some people suggests to calculate pile stiffness by

Punching Shear Ratio in SAFE

SAFE: Punching shear results are displayed as a ratio of maximum calculated shear with respect to capacity. A ratio above 1.0 would indicate capacity was exceeded somewhere along the critical section. The ratio is displayed for each column and each

Area of Reinforcement in SAFE

SAFE reports Area of reinforcement in unit lentgh2/length (mm2/m, cm2/m, and in2/ft). For calculating Number of bars@spacing, do the following: Select Bar Diameter, multiply its area with strip width & divide Strip width by required Area of steel. Example: Assume

Assigning Pier and Spandrel Labeling in ETABS

Wall piers are typically assigned in the model to the wall over height of floor (as in Figure d below). Often, it is more appropriate to assign the pier to the height of wall adjacent to opening (Figure a or
