外墙外保温技术在建筑中的外墙外保温是将保温隔热体系置于外墙外侧,以赋予建筑物良好保温隔热性能的建筑节能措施.除了保温隔热功能以外,由于将绝热体系置于外墙外侧,从而使主体结构所受温差作用大幅度下降,温度变形减小,因而外墙外保温对结构墙体能起到保护作用并可有效阻断冷(热)桥,有利于结构寿命的延长.

Structural Characterization of Composite Structural Insulated Panels for Exterior Wall Applications

Structural sandwich composite panels are extensively used for modular panelized construction. This paper includes the structural characterization of the innovative composite structural insulated panels (CSIPs) developed for the exterior walls of a modularized structure. The facesheets of the CSIPs consist of E-glass fibers impregnated with polypropylene matrix, while the core consists of expanded polystyrene foam. The overall panel dimensions including the thickness of the facesheets and the core were obtained using sandwich composite design theories. Uniaxial compressive loading and high velocity impact (HVI) loading are the most important loading criteria for an exterior wall of a structure. The proposed CSIPs were tested for a compressive load of 13.13 kN/m (900 plf) in this study. The deflection at this load was ～ 3?mm which was within deflection limits of span/150 as prescribed in ACI 318-05 building design code. The proposed CSIP wall panels were also tested under HVI for the loads prescribed by Federal Emergency Management Agency for design of emergency shelters in hurricane prone areas. Based on the HVI testing, CSIPs were able to stop a blunt object projectile traveling at 135 m/s proving its suitability against HVI type of loading.     

High-Performance Vacuum Insulation Panel: Development of Alternative Core Materials

Energy efficiency of the built environment greatly depends on the performance of the insulating materials used in the building envelope construction. Vacuum insulation panels (VIPs) offer excellent thermal resistance properties that can enhance the energy efficiency of the insulating systems and provide savings in energy consumption. However, VIP systems are virtually unknown and rarely used for building construction in North America. There is a need to investigate the use of VIPs in various components of building envelopes and their long-term performance. The National Research Council, Canada, Institute for Research in Construction is investigating a number of fundamental aspects related to the performance and construction of VIPs, which this paper discusses. More specifically, it reviews the underlying basics behind the functioning of VIPs and presents results from the investigation into the development of alternative core materials for VIP construction.     

Role of Insulation Effectiveness on Fire Resistance of Steel Structures under Extreme Loading Events

Fire performance of steel structures is highly dependent on the effectiveness of applied fire insulation. However, insulation materials are susceptible to damage under extreme loading events. A state-of-the-art review on the role of insulation damage on fire resistance of steel structures is presented. Parametric studies on a six-story steel-framed building were carried out to illustrate the effect of insulation damage on fire response of a steel structure. In the analysis, realistic fire scenarios, loading, and failure criteria were taken into consideration. Analysis results indicate that the fire resistance of a steel-framed structure is significantly influenced by the extent of insulation loss, type of fire scenario, and level of lateral load. Insulation damage causes faster deterioration in the structural response of framed buildings under the combined effect of fire and lateral loading. The need for accounting for any insulation damage, arising under extreme loading events, in fire design of steel-framed structures is highlighted, and a performance-based design strategy incorporating fire resistance analysis is discussed.

Numerical Evaluation of Insulation Application to Embankment of Qinghai–Tibetan Highway

In many cases, protecting permafrost from further thaw due to human activities might be the first choice for embankment design in permafrost regions. Two-dimensional finite-element analysis was conducted, in which phase change was taken into consideration to simulate the thermal regime of the Qinghai–Tibetan Highway with extruded polystyrenes. Based on the predicted maximum thaw depth in the following 50 years, a better position for insulation and the optimum thickness of insulation were presented and a reasonable width of insulation and the right construction season were suggested. The applicable range of insulation in embankment engineering of the Qinghai-Tibetan Highway in terms of mean annual air temperature was also suggested and the influence of geothermal field of permafrost on the applicable range of the insulation was discussed.
