General Structural Services

We specialize in structural engineering as related to real estate development including all paving and infrastructure of a development, as well as vertical construction of all types.  This work involves the analysis and design of retaining walls and other land-oriented infrastructure, as well as all elements of vertical structures including foundations, walls,  beams, trusses.  We all inspect damage of all types from a structural engineer's perspective.

Hurricane Force Structural Services

We also offer structural engineering services pertaining to hurricane-prone areas.  This work is focused on designing buildings and infrastructure that can withstand extreme wind, rain, and flooding associated with hurricanes. In these regions, engineers must prioritize safety, durability, and resilience. The aim is to reduce the potential for damage, minimize loss of life, and ensure quick recovery following a hurricane event.

Here are some of the key aspects of structural engineering in hurricane-prone areas:

1. Wind Resistance

  • Wind Load Analysis: Structures need to be designed to resist the intense wind loads associated with hurricanes. Engineers perform wind load calculations based on the local wind speed, which can exceed 150 mph in major hurricanes.

  • Aerodynamic Design: A building's shape and orientation can reduce the effects of wind. Curved or slanted roofs, as well as aerodynamically designed corners, can minimize wind resistance and reduce the risk of wind-induced damage.

  • Reinforced Structures: The use of reinforced steel, concrete, or other high-strength materials can enhance a building’s ability to withstand wind forces. Reinforced roof connections, tie-downs, and shear walls help resist the lateral forces exerted by hurricane winds.

2. Roof Design

  • Roof Anchoring: Roofs are especially vulnerable to wind uplift during hurricanes. Using hurricane clips, straps, or trusses that tie the roof to the walls and foundation can significantly reduce the risk of the roof being torn off.

  • Roof Pitch and Materials: A steeper roof pitch reduces wind resistance, but engineers must also choose durable, weather-resistant roofing materials such as metal, concrete tiles, or impact-resistant shingles.

3. Foundation and Ground Level Protection

  • Elevated Foundations: In flood-prone coastal areas, elevating buildings above the expected flood level is crucial. This can involve using stilts, piers, or concrete slabs raised several feet above the ground.

  • Flood-Resistant Materials: In regions where flooding is common, the use of water-resistant materials in foundations and walls helps minimize damage. Concrete and masonry are commonly used for their durability against floodwaters.

4. Building Shape and Configuration

  • Compact Design: Buildings with a compact shape (i.e., square or circular) are less susceptible to wind forces than irregularly shaped buildings, which create turbulence and pressure points.

  • Continuous Load Path: A continuous load path ensures that wind forces are transferred safely through the building. This includes ensuring that the roof, walls, and foundation are all securely connected.

5. Impact Resistance

  • Shatterproof Windows: Installing impact-resistant windows or shutters is essential in hurricane zones. These prevent debris from breaking windows, which can lead to structural damage and internal flooding.

  • Storm Shutters and Glazing: Special laminated glass or storm shutters protect windows and glass doors from flying debris.

6. Material Selection

  • Corrosion-Resistant Materials: Coastal areas often experience high humidity and salt exposure, so materials that resist corrosion are vital. Stainless steel, aluminum, and treated wood can help prevent rust and decay.

  • Concrete and Steel: Reinforced concrete and steel are highly recommended in hurricane-prone areas due to their strength and resilience. These materials are durable against wind forces, impact, and moisture.

7. Resilience Features

  • Wind-Resistant Facades: External building facades, such as walls and cladding, are designed to withstand wind pressures. Insulated concrete forms (ICFs) or reinforced masonry are often used.

  • Backup Power and Emergency Systems: In hurricane-prone areas, ensuring buildings are equipped with backup power systems, emergency lighting, and accessible escape routes is critical.

8. Hurricane Codes and Standards

  • Building Codes: Many hurricane-prone regions have established strict building codes that require structures to be designed and built to withstand specific wind speeds and storm surges. These codes evolve as more data becomes available about storm behavior and structural performance.

  • International Building Code (IBC): The IBC and its local adaptations set guidelines for wind load and flood resistance, which engineers follow to ensure compliance with safety standards.

  • FEMA Guidelines: The Federal Emergency Management Agency (FEMA) in the United States provides guidelines and recommendations for designing and retrofitting buildings in hurricane-prone regions.

9. Retrofitting Existing Structures

  • Strengthening Older Buildings: Retrofitting involves upgrading older buildings to meet modern hurricane-resistant standards. This may include adding additional bracing, reinforcing roofs, and installing impact-resistant windows.

  • Seismic Considerations: In some hurricane-prone regions, the risk of earthquakes also exists, so retrofitting must address both wind and seismic forces.

10. Sustainability and Green Building

  • Resilient Green Building Materials: Engineers are increasingly exploring sustainable materials that can offer hurricane resistance. For example, bamboo and recycled steel are being studied for their potential in building resilient yet eco-friendly structures.

  • Energy Efficiency: Hurricane-resistant homes can also incorporate energy-efficient features like solar panels, which can continue to function during power outages.

11. Community and Urban Planning

  • Smart Zoning: Communities in hurricane-prone areas must be planned carefully to avoid high-density development in flood-prone zones. Zoning regulations can include restrictions on building near coastal areas or floodplains.

  • Disaster-Resilient Infrastructure: Beyond individual buildings, engineers must also plan resilient infrastructure, such as roads, bridges, and utilities. This includes using materials and designs that can withstand storm surges, high winds, and flooding.
