![]() The panels can be completely discreet, concealed behind walls and/or woodwork including counters, desks and doors.ĪrmorCore® bullet resistant panels are the safest, most affordable and simplest solution for ballistic protection. All levels are UL 752 certified and come backed with our warranty. Each level is rigorously tested to meet or exceed UL specifications for that specific level. Our bullet-resistant panels are available in 8 different levels of protection for safe room applications. These panic rooms can be homes, retail facilities warehouses, offices and more. A flexural creep constant was then proposed to determine the long-term eccentricity of gravity loading in the available combined bending and axial compression equation for PWF design.ArmorCore by Waco Composite manufacture bullet resistant panels for architects designing or remodeling safe rooms. Using the experimental data, the available mathematical and mechanical creep models were evaluated to predict the flexural creep constant (K) of SIP foundation wall subjected to soil pressure over a service life up to 75 years. As such, this paper presents a summary of flexural creep tests conducted to determine the increase in SIP deflection under soil pressure over a period of eight months. Information on the long-term creep behaviour of SIPs under sustained triangular loading, simulating soil pressure, is as yet unavailable. To use the available combined bending and axial compression equation for PWF design, it was observed that the soil pressure would cause short-term and long-term flexural creep deflection of the wall that would decrease the wall capacity. PWF is subjected to gravity loads associated with lateral soil pressure. The maximum deflection equation specified in the Canadian Standard for Engineering Design of Wood, CAN/CSA-O86.09 specifies expressions for the effects of short-term bending deflection on the PWF timber stud walls. SIPs can also be used as permanent wood foundation (PWF) for basements in low-rise residential construction to save in the energy cost. The structural insulated panel (SIP) is an engineered composite product composed of an insulating foam core sandwiched to provide the insulation and rigidity, and two face-skin materials to provide durability and strength. The obtained experimental ultimate compressive loading as well as the long term deflection of the wall under lateral soil pressure / Equivalent Fluid Pressure (EFP) will be used in the force-moment interaction equation to establish the design tables of such wall panels under gravity loading and soil pressure. The ultimate load test results showed that the structural qualification of PWF is “as good as” the structural capacity of the conventional wood-frame buildings. The long-term creep test results led to an empirical creep constant that can be used to obtain the long-term deflection over a specified period of time. The long-term creep test results established the increase in panel total deflection with time. It should be noted that the long-term creep tests were performed over a nine months, followed by loading the tested panels to destruction. The experiment study performed in a manner to comply with applicable ASTM test methods and Canadian Codes for Limit State Design. ![]() Two PWFs sizes were considered in this study, 9’ and 10’ height, respectively, with 4’ width and approx ± 230 mm thick. A Stressed-Skinned Structural made of a wood-composite panel with foam insulation core laminated between two oriented-strand boards of 7/16” thickness, are called Structural Insulated Panel if OSB are in both faces, and Permanent Wood Foundation if one face contains preserved Plywood of 5/8” thickness, SIPs /PWF Foundation SIPs deliver building efficiencies by replacing several components of traditional residential and commercial construction. ![]()
