DOWNLOAD EBOOKGlobal economic losses due to severe weather events have grown dramatically over the past two decades. A large proportion of these losses are due to severe wind storms such as tropical cyclones and tornadoes, which can cause destruction to buildings, houses, and other infrastructure over large areas. To address the growing losses, many new large-scale and full-scale laboratories have been developed. These tools are used to examine the issues that could not be solved with the traditional tools of wind engineering including model-scale boundary layer wind tunnels, simplified standardized product tests, and other methods of analysis. This book presents state-of-the-art results from the development of the many novel approaches being used to mitigate natural disasters around the world.

DOWNLOAD EBOOKThe evolution of modern building materials and development of the curtain wall have led to new opportunities for architectural expression in tall building construction. From wall construction that once consisted of thick, heavy masonry to contemporary metal and glass materials, curtain wall components changed dramatically and required the development of sophisticated water management systems. Early traditional masonry barrier walls controlled water leakage by absorbing water that penetrated the exposed surface and slowly dispersing it as water vapor. As exterior wall design evolved, cavity and curtain walls were designed to accommodate and control water that bypassed the outer surface and channel water to where it could be diverted back to the exterior by internal flashings and weep provisions. Over time, consensus standards were developed to evaluate exterior wall characteristics including air infiltration, water penetration, and structural performance. Mockup testing now provides owners, designers, and contractors with an opportunity to construct and evaluate full-size exterior wall specimens in a laboratory environment. Mockup testing can be an effective construction tool and provide the project team with an opportunity to study full-size details of the exterior wall water management system prior to construction. This paper will briefly discuss the history of water testing and the development of laboratory mockup testing. This paper will also present two case studies, and two different approaches, where water testing was used to evaluate water penetration resistance and critical design details for glass and metal curtain walls.

DOWNLOAD EBOOKConcern has grown, in the past years, of the potentially serious life safety issues related to the performance of building elements such as curtain walls subjected to extreme loading (i.e. bomb blast, high winds). Building curtain walls have traditionally been considered nonstructural elements. However, they can be the first line of defense for occupants of a structure subjected to extreme loading. Improper design and installation procedures or not considering the performance of the curtain wall under extreme loading have been contributing factors to some "failures" of traditional curtain wall systems. This study explores commercially available curtain wall systems and their resistance to low level blast loads. The tested systems are conventional curtain wall systems with two exceptions. The lights are laminated glasses (with a PVB interlayer) that are attached to the mullions with structural silicone sealant. The secured structural silicone-laminated glass combination allows the curtain wall system to absorb the energy of bomb blasts "safely" above the elastic limit. That is, the overload failure mode is designed to minimize injuries and fatalities to building occupants. There have been very few blast tests performed on full-scale conventional curtain wall systems due to the costs involved. Blast testing, while paramount, yields limited information on curtain wall performance over the range of load levels. By applying quasistatic loading on a number of curtain wall test specimens, complete resistance functions are determined experimentally.

DOWNLOAD EBOOKThe purpose of the research presented herein is to correlate structural sealant laboratory test methods with structural test methods for full-scale curtain-wall mockups. Glass panels were adhered around the perimeter of the glass to extruded anodized aluminum frames using multi-component structural silicone sealants. This is considered "four-sided structural silicone glazing." These panels were tested and deflection was recorded at various typical wind load pressures (in the spirit of ASTM E330: Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference, ASTM International, West Conshohocken, PA, 2014, www.astm.org) during multiple cure times of the adhesives. The data has been compared to ASTM C1135 (Standard Test Method for Determining Tensile Adhesion Properties of Structural Sealants, ASTM International, West Conshohocken, PA, 2011, www.astm.org) specimen testing performed at the same cure times. The goal of the research was to better understand how well ASTM C1135 characterizes sealant behavior; and use the data as a platform to predict the performance of full-scale construction. By validating structural performance with cure time, assurance of the structural silicones' integrity during transportation to the site can be confirmed. This data set also took into consideration the time needed for removal of temporary fasteners during a replacement of broken glazing on an existing structure. A unique observation concluded that temporary fasteners could in fact be removed within 1 day of application depending upon site conditions. Two sealants were considered in the testing: a conventional two-part, 10:1 ratio structural silicone sealant that has been in use in commercial glazing for 30 years and a new 1:1 ratio two-part, structural silicone sealant that is currently available in hand-held packaging.
