Category 5 hurricanes are very dangerous, as they cause immense property damage and can even be life-threatening. Several concrete masonry systems have been successfully tested to withstand the 15 lb (6.8 kg) 2 x 4 propelled at 100 mph (161 km/h) (ref. Concrete masonry walls capable of meeting the ICC-500 requirements are presented, as well as the results of impact testing on concrete masonry walls. Net area, An= 36 in./ft (0.08 m/m) When calculating the wind load to be carried by a vertical support, such as a pilaster, a value for K corresponding to the assumed support conditions at the edges of the wall panels and the appropriate wall panel length-to-height ratio is selected from the curves. Houses built with concrete or cinder blocks are reinforced to be wind-resistant, making them an ultimate savior for homes in naturally disastrous areas. To use this calculator, enter the total number of blocks in the project that was estimated previously, and select the width of the block used (6", 8" or 12"). Toll Free: 866-222-2575 For example, rusted rebars can weaken your houses structural integrity. wp = uniform lateral load which approximates the actual wind load transmitted by the walls to the pilasters or cross walls, lb/ft of height (N/m) We are here to make this as easy as possible for anyone.

Insulated concrete blocks (or forms) provide the best protection from windblown debris, to a home and its occupants during 100 mph winds. Assuming that the flexural resistance and rigidity of the walls in both the vertical and horizontal spans are known, the lateral load capacity and the proportion of the lateral load transmitted vertically and horizontally to the edge supports will depend on the restraint developed at the edges, the horizontal to vertical span ratio of the panel, and the distribution of the loads applied to the wall panels. 1st Time Homebuyer, Home Building, House Hunting, If you live in an area that frequently gets tornadoes or hurricanes, the safety of yourself and your home during one of these natural disasters is probably of great concern to you.
