STRUCTURE magazine Base Plate Design for Post Installed

Although no plate is ever truly rigid it is reasonable to assume a column base plate is rigid This is because typical column base plate geometry precludes any significant plate deformation or bending under loading The rigid plate assumption permits the stress strain behavior of the anchor bolts and the concrete to be modeled as elastic

Axial Loading an overview ScienceDirect Topics

Axial loading is defined as applying a force on a structure directly along an axis of the structure As an example we start with a one dimensional 1D truss member formed by points P 1 and P 2 with an initial length of L Fig 1 2 and a deformed length of L′ after axial loading is applied The average axial engineering strain is defined as the total amount of deformation L′ − L
