Webinar HAKI - Perancangan Struktur Baja Tahan Gempa

Introduction

This tutorial provides a comprehensive guide on designing earthquake-resistant steel structures, based on insights from the webinar "Perancangan Struktur Baja Tahan Gempa" featuring Dr. Ir. Muslinang Moestopo. Understanding these principles is essential for engineers and architects involved in construction in seismic zones.

Step 1: Understand Seismic Forces

Familiarize yourself with the types of seismic forces that affect structures, including

• Ground shaking
• Ground displacement
• Recognize that these forces can significantly impact structural integrity and safety.

Step 2: Learn About Structural Design Principles

Study the fundamental principles of structural design for earthquake resistance

• Ductility: Ensure that structures can deform without collapsing.
• Redundancy: Incorporate multiple load paths to prevent failure.
• Strength: Use materials and designs that can withstand high stress.
• Consider how these principles apply to steel structures specifically.

Step 3: Analyze Site Conditions

Assess the geological and soil conditions of the construction site

• Conduct soil tests to determine bearing capacity and potential liquefaction.
• Evaluate the proximity to fault lines and historical seismic activity.

Step 4: Apply Design Codes and Standards

Familiarize yourself with relevant design codes that govern earthquake-resistant construction, such as

• ASCE 7 (American Society of Civil Engineers)
• Eurocode 8
• Ensure compliance with local building regulations and seismic design guidelines.

Step 5: Create a Robust Structural Model

Use software tools to create a structural model

• Input material properties, loading conditions, and boundary conditions.
• Perform dynamic analysis to simulate how the structure responds to seismic events.
• Common software options include SAP2000, ETABS, and ABAQUS.

Step 6: Optimize Structural Elements

Design structural components, focusing on

• Beam and column sizes
• Connections and joints
• Ensure that all elements work together to dissipate energy during an earthquake.

Step 7: Conduct Performance-Based Design

Implement performance-based design approaches to assess how the structure will perform under different seismic scenarios

• Define performance objectives (e.g., life safety, immediate occupancy).
• Use nonlinear analysis techniques to evaluate structural behavior.

Step 8: Review and Revise Design

Regularly review the design for potential weaknesses

• Conduct peer reviews or use a third-party evaluator.
• Make necessary adjustments based on feedback or updated codes.

Conclusion

Designing earthquake-resistant steel structures requires a deep understanding of seismic forces, structural principles, and compliance with design codes. By following these steps, engineers can create safe and resilient buildings capable of withstanding seismic events.
