## Course Learning Outcomes (CLO)

 CLO:1            Understand the basic concepts of earthquake-resistant design. CLO:2            Have skills for computer aided design of earthquake-resistant design of concrete structures.

## Introduction

• Introduction to earthquake engineering (basic concepts only from design point of view)

• Base shear numerical

## Super Structure Analysis and Design using ETABS

• Background: Concepts of architectural drawings; coordinate / grid system; structural layout of beams, columns and shear walls (if any); earthquake- resistant design

• ETABS introduction; grids layout; material properties; member sizes, modifiers and other details

• Geometry layout (beams, columns, shear walls, slabs); replication (linear, mirror, story); supports

• Basic load cases (Dead, superimposed dead, live, roof live, soil (if any) and earthquake); mass-source

• Factored load combinations (considering eccentricities in all directions and using all code clauses)

• Applying basic loads (point, uniformly distributed, varying lateral and area loads)

• Checking model errors; analysis options; model analysis

• Evaluation of analysis; performing concrete design

• Extracting column design

• Extracting beam design

• Extracting shear wall design
• Extracting slab design

## Sub Structure Analysis and Design using SAFE

• Concepts of allowable bearing capacity (net, gross and effective); examples

• Exporting ETABS file for SAFE foundation model; Importing ETABS data/analysis; material and soil properties; foundation type and thickness; applying additional loads (if required)

• Preliminary foundation layout

• Factored load combinations (considering eccentricities in all directions and using all code clauses)

• Evaluation of analysis and design; checking bearing pressures and satisfying foundation sizes

• Extracting foundation design
