Blast-Resistant Design for Property and Building Owners

Property and building owners and managers should employ a comprehensive approach to blast design:

• Threat Assessment: We work with our clients to define the potential threats, considering factors such as the type and size of explosive, standoff distance, and potential points of attack.
• Performance Objectives: We establish clear performance objectives, defining the acceptable level of damage for different blast scenarios. This might range from minimal structural damage to ensuring life safety.
• Advanced Analysis: We use sophisticated software to model the blast event and analyze the structural response. This includes:
• Blast load modeling: Simulating the complex pressure-time history of the blast wave.
• Nonlinear dynamic analysis: Assessing the structural behavior under extreme loading conditions, considering material nonlinearities and large deformations.
• Design Strategies: Based on the analysis results, we implement design strategies to enhance the blast resistance of the structure. These may include:
•  Ductile detailing: Designing connections and members to deform in a controlled manner, absorbing energy and preventing brittle failure.
•  Stand-Off Distance: Locate parking and roadways to decrease the bomb blast pressures.
•  Redundancy: Build in redundant load paths to minimize the likelihood of progressive collapse.
• Material Selection: Builders should select materials with high strength, ductility, and energy absorption capacity. This may include:
• Ductility: Utilize ductile materials such as steel to absorb the energy from a blast.
• Mass: Utilize heavy cladding to absorb the energy from a blast.

Blast Design for Defense

In today’s world, the threat of explosive attacks is a serious concern for a wide range of structures, from government buildings and military installations to critical infrastructure and commercial properties.

As a structural engineering company, we understand the importance of designing and constructing buildings that can withstand the devastating effects of blasts.
Understanding the Challenge

Blast events generate extreme loads in a very short time, creating complex dynamic forces that can cause catastrophic damage to conventional structures. These forces include:

•     Airblast: The rapid overpressure wave generated by the explosion.
•     Ground shock: The seismic waves transmitted through the ground.
•     Fragmentation: High-velocity debris propelled by the blast.

The goal of blast design is to mitigate these effects, protecting both the structure itself and the people inside.

Snow Removal 101 for Parking Structures

Do you maintain a parking structure or parking garage at your facility?

When winter hits, are you truly prepared to take care of the snow and ice buildup?

Before the snow hits, there are some items to add to your to-do list that will make snow clearing easier and will help ensure you avoid costly repairs when the snow finally melts.

1. Don’t use metal or steel snowplow blades in the garage! Use urethane or heavy rubber edges.
2. Only use de-icing agents that are parking garage-friendly! Sodium acetate, potassium acetate, and calcium magnesium acetate are good to use in advance of snowfall. Avoid sodium chloride (rock salt), calcium chloride, and ammonium nitrate in a garage as these accelerate corrosion of reinforcing!
3. Don’t store large piles of snow on the roof. Large snow piles get heavy over time and can quickly exceed the live load limits of the structure or garage.
4. In between snowfalls, make it a habit to use snow melt machines or over-the-side dumping to remove large snow piles from the garage.

IEI Specializes in Parking Garage Restoration

We’ve been helping owners reduce parking garage restoration costs since 1995. Unlike most other building systems that are protected by a conditioned building envelope, parking structures are directly exposed to the elements which results in exponential or accelerated deterioration. Therefore, early and inexpensive parking garage restoration practices produce a ROI much higher than that of other building systems.

Preventing EV Fires in Parking Structures

To mitigate the risks associated with EV fires in parking structures, several measures can be implemented:

• Regular Inspections: Conduct routine inspections of charging infrastructure, cables, and connectors to identify and address potential hazards.
• Fire Suppression Systems: Consider installing fire suppression systems specifically designed for EV fires, such as those using inert gases or foam that do not harm batteries.
• Emergency Procedures: Develop and implement emergency procedures for handling EV fires, including evacuation plans and protocols for first responders.
• Ventilation: Improve ventilation in parking structures to facilitate smoke removal and reduce the spread of fire.
• Battery Management Systems: Advancements in battery management systems can help prevent thermal runaway by monitoring battery temperature, state of charge, and other critical parameters.

While EVs offer many advantages, it is essential to address the potential fire hazards associated with their use in parking structures. By taking proactive steps to prevent fires and ensure proper emergency response, we can create safer environments for both EV owners and building occupants.

Understanding the Risks of EV Fires in Parking Structures

The rise of electric vehicles (EVs) has brought about a significant shift in the transportation landscape. While EVs offer numerous benefits, such as reduced emissions and improved fuel efficiency, they also present unique safety concerns, particularly in enclosed spaces like parking structures. One of the most pressing issues is the risk of fire. This blog post will delve into the factors that contribute to EV fires in parking structures and explore strategies to mitigate these risks.

Unique Fire Risks of EVs

Unlike traditional gasoline-powered vehicles, EVs rely on lithium-ion batteries, which are highly energy-dense. While these batteries offer excellent performance, they can also be prone to thermal runaway under certain conditions. If a battery cell becomes damaged or overheated, it can trigger a chain reaction, leading to a rapid increase in temperature and the release of flammable gases. This can result in a fire that is difficult to extinguish and can spread quickly in a confined space like a parking structure.

Preventing Water Intrusion

To protect concrete structures from water intrusion, it is essential to take preventive measures. These may include:

• Proper design and construction: Ensuring that concrete structures are designed and constructed to be water-resistant, with adequate drainage and waterproofing measures.
• Regular inspections: Conducting regular inspections to identify and address any signs of water intrusion.
• Repairing cracks and joints: Promptly repairing any cracks or joints that may allow water to enter the structure.
• Applying water repellent sealers: Applying water repellent penetrating sealers makes the concrete surface hydrophobic which water absorption into the structure. 
• Improving drainage: Ensuring that the surrounding area is well-drained to prevent water from pooling around the foundation.

By understanding the risks posed by water intrusion and taking appropriate preventive measures, building owners and managers can help to protect their concrete structures and ensure their long-term durability.

Hiring engineering professionals to investigate water damage is key. Water intrusion engineers have modern technology like thermal imaging, and equipment to detect excessive moisture or mold spores in the air.
