This presentation summarizes the analysis and design of a three story reinforced concrete building using ETABS software. It includes modeling the building, applying loads such as dead, live, wind and earthquake loads, analyzing the structure for stability, and designing beams and columns. Screenshots are provided of the 3D building model, applied loads, and steel schedules for beams and columns on each floor.
3. What is ETABS?
ETABS stands for Extended
Three-Dimensional Analysis of
Building System. It is a
sophisticated and suitable special
purpose analysis and design
program particularly developed
for building systems. Modeling
tools and templates, code-based
load prescriptions, analysis
methods and solution techniques,
all coordinate with the grid-like
geometry unique to this class of
structure. Basic or advanced
systems under static or dynamic
conditions may be evaluated using
ETABS.
