Resilient Solutions: Seismic Design for Lateral Force-Resisting Systems in Pre-engineered Buildings

In the ever-evolving landscape of PEB construction, designing structures that stand the test of time and nature is paramount. For businesses operating in seismic regions, ensuring the safety and resilience of steel buildings against earthquakes is not just a regulatory necessity but a competitive advantage. At Everest Steel Building Solutions, we understand the critical role lateral force-resisting systems (LFRS) play in seismic design and we are here to help you stay ahead of the curve.

Let’s explore why LFRS is the backbone of seismic resilience and how incorporating cutting-edge solutions can future-proof your PEB manufactured projects.

Steel: The Material of Choice in Seismic Zones

PEB manufacturers dominate seismic regions for a reason: their inherent strength, flexibility and ductility make them a preferred choice for resisting earthquake forces. But these advantages can only be maximized with a well-designed LFRS that ensures structural integrity during seismic events.

When done right, LFRS not only protects lives and property but also minimizes downtime and repair costs, a crucial consideration for businesses focused on operational continuity.

Optimizing Your Lateral Force-Resisting Systems

  1. Tailoring the Right System to Your Needs
Selecting the appropriate LFRS is the foundation of seismic resilience. Here are the primary systems:
  • Moment-Resisting Frames (MRFs): These frames provide exceptional ductility, allowing structures to absorb and dissipate seismic energy effectively. Ideal for projects requiring open floor plans.
  • Braced Frames: Offering enhanced stiffness and strength, braced frames, including concentric and eccentric types are perfect for industrial and high-rise applications.
  • Steel Plate Shear Walls (SPSWs): These systems combine strength and energy dissipation, delivering robust performance for seismic forces while optimizing material use.
  • Dual Systems: A hybrid approach that integrates MRFs with braced frames or shear walls for enhanced redundancy and safety.

  1. Prioritizing Code Compliance and Beyond
Seismic design standards such as ASCE 7 and AISC 341 provide a framework, but staying ahead means designing for performance rather than minimum compliance. Our solutions ensure that your Peb buildings meet and exceed these standards, maximizing safety and efficiency. Key considerations include:
  • Load Path Continuity: Seamless transfer of seismic forces from the roof to the foundation.
  • Response Modification Factor (R): Selecting systems with appropriate ductility and energy dissipation.
  • Drift Control: Safeguarding non-structural elements by limiting lateral deflection.

  1. Engineering for Ductility and Strength
Ductility is the hallmark of seismic-resistant design. Properly detailed connections, capacity-designed components and high-quality materials ensure structures remain safe and functional even under extreme conditions. Our team emphasizes capacity-protected designs to prevent brittle failures and maintain structural integrity.

Performance-Driven Seismic Design

For PEB manufacturers seeking to differentiate themselves, performance-based design (PBD) is a game-changer. By focusing on specific outcomes, like minimizing damage or ensuring immediate occupancy, PBD allows you to customize resilience to your operational priorities. Our PBD expertise includes:

  • Energy Dissipation: Integrating damping systems to reduce seismic demands.
  • Advanced Analysis: Leveraging nonlinear dynamic and pushover analyses for optimized performance.
  • Resilience Planning: Ensuring post-earthquake repairability and operational continuity.

Leveraging Innovative Technologies

Seismic resilience is not just about materials and systems; it’s also about leveraging the latest technologies:

  • Base Isolation: Decouples the structure from ground motion, reducing seismic impact.
  • Damping Devices: Tuned mass, friction, or viscous dampers enhance energy absorption.
  • Real-Time Monitoring: Smart sensors provide actionable insights for ongoing safety.

By integrating these technologies, Everest Steel Building Solutions helps clients achieve smarter, safer and more sustainable pre-engineered buildings solutions.
