Bow Truss System Repair Walkthrough

Alpha Structural specializes in handling complex structural issues that demand expert solutions. Recently, our experienced team successfully completed an extensive project in Silverlake on Sunset, addressing severe structural damage in the bow truss roofing system of a commercial property—a former 99¢ store.

Understanding the Bow Truss System

A bow truss is a specialized roofing framework engineered to efficiently span large, open spaces without internal supports. Its characteristic bow shape enables expansive commercial interiors, making it ideal for warehouse and retail spaces. The system, while lightweight, is robust, with bottom framing elements enduring substantial tension to sustain structural integrity.

Bow truss systems first gained popularity in the early 20th century, revolutionizing industrial and commercial building design. Their ability to span considerable distances without intermediate supports makes them particularly suited for warehouses, factories, and retail spaces where unobstructed interior space is essential. The tension and compression forces within a bow truss require meticulous maintenance and care to prevent structural failures.

Expert Inspection and Damage Assessment by Alpha Structural

Alpha Structural’s project, spearheaded by our VP of Development, Erinn Rusnak, began with an initial inspection identifying seven areas of visible damage. Excessive weight from layers of outdated ceiling materials, accumulated over time by previous tenants, severely compromised the truss framing, leading to fractures and splintering.

Upon removing these materials, our meticulous assessment revealed twelve additional critically damaged areas, indicating the system was nearing the end of its structural lifespan. The significance of early damage detection cannot be overstated—delayed repairs can exacerbate structural problems, leading to costly consequences and potential safety hazards.

Rapid Response Following Earthquake Damage

Amid our engineering and planning phase, an earthquake occurred, significantly intensifying the structural damage. Understanding the urgency, Alpha Structural rapidly secured necessary approvals and swiftly implemented a robust temporary shoring system, ensuring immediate structural stability.

The seismic event highlighted the importance of prompt and proactive structural maintenance. Earthquakes can rapidly degrade already compromised structures, underscoring the critical need for immediate expert intervention. Alpha Structural’s swift and precise response minimized the risk of further damage and potential collapse.

Customized Engineering and Comprehensive Structural Repairs

Every bow truss repair demands a custom-engineered solution. Alpha Structural’s expert engineering team meticulously designed a precise, site-specific repair plan, offering a highly cost-effective alternative to complete roof replacement.

The carefully executed repairs involved removing and replacing damaged framing elements, reconditioning original steel anchors, and connecting new framing directly to existing anchoring points. This approach allowed us to substantially reduce costs.

Customized engineering ensures repairs address specific vulnerabilities without compromising the broader structural integrity. Alpha Structural’s tailored approach not only reduces overall project costs but also significantly extends the longevity and resilience of the repaired structure.

Innovative Structural Solutions

Alpha Structural emphasizes innovation in all repair projects. By strategically linking new framing elements with existing anchoring points, our team avoided extensive, invasive masonry repairs. This innovative strategy guaranteed structural reliability, efficiency, and historical preservation.

Innovation is central to Alpha Structural’s philosophy. Our ability to develop creative, effective solutions stems from deep industry knowledge combined with practical, hands-on experience. By continuously refining our methods, we remain at the forefront of structural repair and reinforcement.

Expert Shoring: A Critical Safety Measure

An essential aspect of our repair process is expert shoring. Alpha Structural carefully planned and installed comprehensive shoring solutions to stabilize vertical supports, angled supports, and tension cables, ensuring structural integrity throughout the repair process.

Proper shoring is critical to maintaining safety during repairs. Without expert shoring, removing or adjusting structural elements could lead to catastrophic failures. Our meticulous planning ensures each repair phase is safely executed, maintaining structural stability throughout.
