Zero Compression Element

When we want to model tension cable rods or any member with zero compressionĀ  and want to use finite element model for this purpose then follow the procedure below. This procedure is written considering CSI products (SAP or ETABS) but

Where is the Base?

ASCE 7-05 defined the base for seismic design as: “The level at which the horizontal seismic ground motions are considered to be imparted to the structure”. Most of the times this isĀ misinterpretedĀ or misunderstood that where the base is considered when

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
