DESIGNING SAFE ROOMS AND SAFE HOMES WITH LOGIX 2 ©2012 LOGIX Insulated Forms Ltd. Hurricanes and In fact, 2011 is proving to be a record year in high wind regions to be for tornadoes costing billions in property based on basic wind speeds that may be tornadoes have damage, and hundreds of lives lost. up to 170 mph (200 mph in the Florida progressively caused Code). Statistically, this covers As we continue to rebuild in the paths approximately 90% of all wind speeds more damage to of hurricanes and tornadoes, stronger experienced in the US including those property, personal and more durable building materials generated by hurricanes and weaker injury and loss of life than traditional framed or masonry wall tornados. construction needs to be considered. than any other natural Basically, these buildings need to be more Buildings in compliance to the model disaster in the United resistant to extreme wind events than building codes are designed and what is currently required by building constructed with adequate wall to , States. codes. and wall to footing connections, so that a continuous load path is provided to Due to its many benefits, LOGIX has been transfer wind loads from the framing gaining popularity in the building industry members to the . However, as an alternative to framed or masonry with the exception of construction. Over the years, LOGIX has openings, model building codes have proven to be quick and easy to install no requirements for the protection of while providing the built-in insulation exterior and roofs from wind- and . The thick rigid foam borne debris. As a result, buildings hit insulation and concrete core also creates a from flying debris during high wind events high energy efficient wall system. can experience a breach in the building envelope through the exterior walls, even The added benefit of a solid reinforced within wind speeds the building was concrete core protected by a layer of rigid designed for. foam makes LOGIX one of the strongest, most durable wall systems available, and A breach in the building envelope during ideal for buildings and safe rooms in high high wind events can greatly increase wind-prone regions. the pressure experienced by the building, which can lead to possible structural This document discusses the use of damage and potential harm to building LOGIX in the design and construction of occupants. For the most part, minimum buildings and safe rooms in high wind- requirements of model building codes prone regions. In addition, engineered are meant to protect the loss of wind load tables and FEMA compliant property rather than the loss of life. ready-to-use safe construction plans are noted as a design aid specific for Generally, the costs associated to design LOGIX. and construct a debris resistant home, or larger building, with the intent to fully protect its building occupants, make it Buildings Constructed to impractical to build. Which is likely the Model Building Codes reason there are no wind-borne debris Depending on the geographic location impact protection requirements for of the building, the model building codes exterior walls and roofs in model building require the design and construction of codes.

For the most However, with exterior walls being the walls where the design wind speed main structural support for buildings, is greater than 150 mph. The table part, minimum stronger, more durable walls offer more includes wind speeds of 200, 250, 275 requirements of model protection to building occupants against and 300 mph for LOGIX walls of varying debris impacts, and can reduce the costs thicknesses and wall heights.

In addition, air infiltrating and will offer more safety than framed or through framed walls during extreme masonry walls. However, it is important to wind events can increase the stress on note that special attention should be paid the building. Masonry construction to the connection details for wind loads requires full grouting and reinforcement. not covered in building codes. Connection In comparison, LOGIX walls are naturally details between the wall to footing, and strong, durable and airtight structures that wall to roof, will depend on a number resist high wind loads, and debris impacts of factors such as wind load, height without the need to further strengthen and shape of building. A local licensed the wall. engineer should be consulted if the design of the building is outside the scope of the History has shown that reinforced model building codes. concrete structures, like those built with LOGIX, are often the only buildings left standing in the aftermath of a hurricane Safe Rooms or tornado. Typically buildings are not designed to fully withstand wind-borne debris impacts Despite the lack of wind-borne debris generated by hurricanes and tornados. protection in the model building codes for walls and roofs, using LOGIX can help Wind driven debris presents the greatest ensure buildings stay intact and provide hazard to building occupants and to a higher level of safety, during extreme building structures during a tornado wind events. or hurricane. In cases of extreme wind events, building occupants should evacuate to safe rooms designed to Logix Wind Load Tables protect building occupants. Since reinforced concrete is the structural component of LOGIX, buildings Every component of a , from constructed with LOGIX can be designed the roof to the foundation, is designed for higher wind loads than what is to withstand missile impacts and required by code. associated wind loads up to 250 mph. This represents more than 99% of all To aide designers and builders, Table 3B tornados known to have occurred in the in Section 6 of the LOGIX Design Manual United States, and higher than Category 5 offers a wind load table for above-grade hurricanes.

However, ICFs construction of safe rooms. wind loads, including debris impacts, than were the only wall system that showed typical framed and masonry structures. no signs of damage to the structural As an aid to home owners, builders and Well recognized for their inherent component of the wall assembly–no designers, LOGIX has developed a set of resistance to large wind loads, and debris visible damage to the concrete core of the construction plans for the construction of impacts, ICFs are the perfect choice for ICFs tested. residential and small business safe rooms constructing buildings in high wind prone using LOGIX.
