Structural Scheme Setting and ETABS Analysis of RCC (Reinforced Cement Concrete) Buildings Course

Lesson 1 • Structural Systems and Load Paths

Examines frame, shear wall, and flat-slab systems and how gravity and lateral loads travel through them. Connects system choice to building performance.

Lesson 2 • Building Geometry and Grid Systems

Introduces structural grids, bay spacing, story heights, and plan regularity. Provides the geometric vocabulary needed for scheme layout.

Lesson 3 • Structural Members and Their Functions

Defines beams, columns, slabs, walls, and foundations and their individual roles. Prepares students to assign member types correctly during modeling.

Lesson 4 • Introduction to RCC Structural Concepts

Covers concrete and steel interaction, stress-strain behavior, and ductility. Establishes the material basis for all subsequent structural decisions.

Lesson 1 • Reading and Interpreting Architectural Drawings

Teaches extraction of structural information from floor plans, sections, and elevations. Directly enables accurate scheme setup in subsequent sections.

Lesson 2 • Scheme Documentation and Review

Formalizes the structural scheme into annotated drawings and a member schedule. Prepares deliverables for peer review and client communication.

Lesson 3 • Lateral System Selection and Placement

Guides selection and positioning of shear walls and cores for wind and seismic resistance. Establishes the lateral scheme before model creation.

Lesson 4 • Structural Scheme Layout Principles

Covers column placement logic, beam layout strategies, and slab panel organization. Ensures the scheme is efficient, buildable, and analysis-ready.

Lesson 1 • Section Property Definition

Creates frame and shell section properties for beams, columns, slabs, and walls. Links section definitions to the material properties set in the previous section.

Lesson 2 • Model Templates and File Management

Uses built-in templates to accelerate setup and establishes a file-saving and backup protocol. Protects model integrity throughout the project lifecycle.

Lesson 3 • Material Property Definition

Defines concrete and rebar material properties including strength, modulus, and weight. Accurate material data is essential for correct analysis results.

Lesson 4 • Units, Grid, and Story Configuration

Configures unit systems, defines structural grids, and sets story data including heights and master stories. Creates the spatial framework for all model objects.

Lesson 1 • Foundation and Support Modeling

Defines base supports, spring foundations, and mat slab elements at the ground level. Proper boundary conditions directly affect global model behavior.

Lesson 2 • Model Geometry Verification

Uses ETABS check tools to detect unconnected nodes, overlapping elements, and missing assignments. Eliminates geometry errors before load application.

Lesson 3 • Modeling Slabs and Floor Systems

Creates slab areas, defines membrane and shell behavior, and handles openings and voids. Accurate slab modeling governs load distribution and diaphragm action.

Lesson 4 • Drawing and Placing Frame Elements

Draws beams and columns using point, line, and grid-snap tools with correct section assignments. Establishes the primary skeleton of the structural model.

Lesson 1 • Load Combinations Setup

Creates strength and serviceability load combinations per design standard requirements. Correct combinations drive all design checks performed in later chapters.

Lesson 2 • Seismic Load Definition

Sets up equivalent static and response spectrum seismic loads using site and structural parameters. Prepares the model for both static and dynamic seismic analysis.

Lesson 3 • Wind Load Definition and Application

Configures wind load parameters using code-based pressure coefficients and applies them to the building envelope. Produces realistic lateral wind demand on the structure.

Lesson 4 • Load Pattern and Load Case Fundamentals

Distinguishes load patterns from load cases and sets up the load pattern library. Correct setup prevents errors in all downstream combinations and analysis.

Lesson 1 • Reviewing Force and Stress Results

Extracts bending moments, shear forces, and axial loads in beams, columns, and walls. Validates that force distributions match expected structural behavior.

Lesson 2 • Reviewing Deformation and Drift Results

Examines story displacements, inter-story drift ratios, and deformed shapes for all load cases. Drift results are benchmarked against code serviceability limits.

Lesson 3 • Analysis Options and Run Settings

Configures analysis type, solver options, and modal parameters before execution. Proper settings ensure efficient and accurate analysis for the building type.

Lesson 4 • Modal Analysis and Mass Participation

Reviews mode shapes, natural periods, and cumulative mass participation ratios. Confirms that sufficient modes are captured for accurate seismic response.

Lesson 1 • Column Design and Interaction Diagrams

Designs columns under combined axial and biaxial bending and reviews interaction diagram plots. Confirms column adequacy for all governing load combinations.

Lesson 2 • Slab and Wall Design

Performs slab flexural design and wall pier design, extracting reinforcement per unit width. Covers punching shear checks for flat slabs.

Lesson 3 • Design Preferences and Code Selection

Sets the concrete design code, design preferences, and overwrites at the global and member level. Correct preferences govern all reinforcement calculations in the chapter.

Lesson 4 • Beam Design and Reinforcement Output

Runs beam design, reviews flexural and shear reinforcement demands, and interprets design ratios. Identifies beams requiring resizing or scheme revision.

Lesson 1 • Structural Calculation Documentation

Organizes hand calculations, code references, and model assumptions into a structured calculation package. Ensures traceability and auditability of all design decisions.

Lesson 2 • ETABS Report Generation

Configures and exports analysis and design reports including tables, diagrams, and summaries. Covers report customization for different audience types.

Lesson 3 • Extracting and Presenting Key Results

Identifies the most critical results—drift, design ratios, reinforcement demands—and formats them for clear communication. Prepares concise technical summaries.

Lesson 4 • Drawing Coordination and Output

Exports model geometry to structural drawing formats and coordinates with detailing teams. Bridges the gap between analysis output and construction documents.
