ETABS 22 Tutorial Modelling ,Analysis and Design Multi-Story RC Shear Wall Structure

ETABS 22 Tutorial Multi-Story RC Structure Objective: To provide a step-by-step guide for modeling, analyzing, and designing a reinforced concrete (RC) multi-story building using ETABS 22. The tutorial will cover key aspects from basic modeling to advanced analysis techniques, including load application, analysis, and structural design according to relevant building codes. ________________________________________ 1. Introduction to ETABS 22 Objectives: • Familiarize users with the ETABS 22 interface and its features. • Introduce basic modeling concepts specific to RC structures. • Brief overview of the workflow (Modeling → Loads → Analysis → Design). Key Topics: • Introduction to ETABS: o Overview of ETABS software and its application in structural engineering. o Key features and advancements in ETABS 22. o Overview of the working interface: menu bar, toolbars, model window, and output window. o Navigation through the interface and customization of views. ________________________________________ 2. Modeling a Multi-Story Building Objectives: • Guide users through the step-by-step process of modeling a multi-story RC structure. • Introduction to grids, story definitions, material properties, and section assignments. Key Topics: • Creating a New Model: o Setting up grid systems (global and local grids). o Defining story levels and creating typical stories. • Material Properties: o Define material properties for concrete (f’c), reinforcement steel (fy), etc. o Assigning material properties to elements. • Section Properties: o Define cross-sections for columns, beams, and slabs. o Modeling wall elements and their section properties. • Structural Layout: o Modeling columns and beams for a regular floor plan. o Creating floor slabs (one-way and two-way slabs). o Adding shear walls and core walls (if applicable). ________________________________________ 3. Load Definitions and Assignments Objectives: • Define and apply various loads to the structure, including dead loads, live loads, and wind/seismic loads. Key Topics: • Load Patterns: o Define different load patterns (Dead, Live, Wind, Seismic). o Load cases and combinations according to building codes (ASCE, Eurocode, etc.). • Assigning Loads: o Applying uniform floor loads (dead and live loads). o Line loads for beams and wall loads. o Application of point loads on specific elements. o Load assignment for lateral loads (wind and earthquake loads). • Automatic Load Generation: o Introduction to the ETABS automatic wind and seismic load generation. o Assigning wind load parameters (height, terrain category, etc.). o Seismic load parameters (zone factor, importance factor, response reduction, etc.). ________________________________________ 4. Structural Analysis Objectives: • Perform structural analysis and understand the analysis results. Key Topics: • Setting up the Analysis: o Run the structural analysis in ETABS. o Understanding the different solver options (static, dynamic, linear, non-linear). • Analyzing the Model: o Interpret deflections and deformations. o Review internal forces in beams, columns, and slabs (bending moments, shear forces, axial forces). • Lateral Load Analysis: o Understanding the behavior of the structure under lateral loads (wind and earthquake). o Drift calculations and checking for code compliance. ________________________________________ 5. Design of RC Elements Objectives: • Design RC elements (columns, beams, slabs, and shear walls) based on building codes. • Modify the model based on design results, such as reinforcement requirements.
