Base Plate Design

Fixed Steel Base Plate Design Acc. To AISC-LRFD

Introduction

This calculator performs the design and verification of fixed steel base plates according to AISC 360-10 (LRFD) and ACI 318-14 specifications. Enter the required dimensions, material properties, and applied loads to calculate the base plate thickness, anchor bolt capacity, concrete bearing strength, and verify all design checks including tension, shear, and interaction effects.
