Equipment for characterizing wind-drivin rain loads for mid-rise buildings

通过NSERC RTI申请申请的资金是为了支持最近批准的NSERC创新木制品和建筑系统战略网络（NEWBuildS）计划的一个研究项目。这个子项目的目标是量化加拿大关键地区中层建筑的风雨荷载，这些建筑代表了广泛的风雨特征。建议的研究项目将产生不同悬挑结构的中层建筑的风力荷载的新数据。计划在三个地理位置，卑诗省低陆平原，魁北克省（或安大略省）和沿海地区进行风驱动降雨测量。共有九栋中层建筑将安装风力降雨测量设备。收集的数据将使研究小组能够量化与当地地形有关的风驱动雨荷载，并开发一种湿润模式，用于评估悬挑设计的有效性。通过现场监测收集的数据将用于CFD模型的基准测试。一旦模型得到验证，它将被用于产生不同大小、几何形状、悬挑结构、当地环境和地理位置的中高层建筑的风雨荷载大小和湿润模式。综合这些研究结果，就不同地理位置的悬挑宽度和结构提出建议。这些知识对于开发技术解决方案和稳健的设计至关重要，以确保中层木结构建筑的耐久性，然后可以将其整合到建筑设计指南，规范和标准中，并有助于推进建筑创新。要求的设备包括气象站、定制的行车雨量计、数据记录仪及附件。除了NSERC的NEWBuilds项目外，预计该设备还将用于开发加拿大气候的风雨数据库和设计工具，用于预测建筑物上的风雨。

The fund being requested through this NSERC RTI application is to support a research project planned in the recently approved NSERC Strategic Network on Innovative Wood Products and Building Systems (NEWBuildS). The objective of this sub-project is to quantify wind-driven rain loads for mid-rise buildings in key areas of Canada that represent a wide range of wind-driven rain characteristics. The proposed research project will generate new data on wind-driven load on mid-rise buildings with various overhang configurations. Wind-driven rain measurements in three geographic locations, the Lower Mainland of BC, Quebec (or Ontario), and the Maritimes are planned. A total of nine mid-rise buildings will be instrumented with equipment for wind-driven rain measurements. The data collected will enable the research team to quantify wind-driven rain load in relation to local topography and also develop a wetting pattern that is useful for assessing the effectiveness of overhang designs. Data collected through this field monitoring will be used to benchmark a CFD model. Once the model is validated, it will be used to generate wind-driven rain load magnitudes and wetting patterns on mid-rise buildings of various sizes, geometries, overhang configurations, local surroundings and geographic locations. Synthesis of the results will lead to recommendations on overhang widths and configurations in different geographic locations. Such knowledge is critical in developing technical solutions and robust designs for ensuring durability performance of mid-rise wood-frame construction, which can then be integrated into building design guidelines, codes and standards and also help advance building innovation. Equipment requested includes weather stations, customized driving rain gauges, data loggers with accessories. In addition to the NSERC NEWBuilds project, it is expected that the equipment will be used for future studies on development of a wind-driven rain database for Canadian climates and design tools for predicting wind-driven rain on buildings.
