This Small Grant for Exploratory Research (SGER) Network for Earthquake Engineering Simulation Research (NEESR) payload project will utilize the experimental test set-up of the NSF-funded project (CMMI-0530759) entitled "NEESR SG: Development of Performance Based Tsunami Engineering, PBTE" at the NEES tsunami wave basin at Oregon State University during June - December 2007. The objective of this payload project is to install residential structural models, at a larger-scale than the mid to high-rise structures tested by the SG researchers on the other side of the wave basin, to investigate impact due to wave loading and run-up (applications to tsunami engineering) and pressure/wind driven surge (applications to hurricane engineering and science). The payload project will install two single-family dwelling models beside each other on a flat surface above the waterline representing coastal property or a structure slightly inland. The following new knowledge will be generated by this payload project: (1) information on fluid impact loads as a function of different wave heights and ground slopes on residential structures to enable the development of dimensionless charts for use by practitioners/planners and to facilitate innovative construction techniques in coastal regions; (2) an understanding of the load transfer mechanism and uplift forces on residential structures during wave and surge loading, both of which are not understood currently; and (3) the relationship of scale model pressure to full-scale prototype damage through existing methods, formulations, and minimal assembly testing.Intellectual merit: Whole woodframe models have never been tested in a tsunami wave basin; thus new information about the response of woodframe structures subjected to tsunami loading will be generated and made available to the earthquake engineering and broader science community. Broader impacts: Experimental results will be made available to researchers, practitioners, designers, and public policy officials via the NEES central data repository operated by NEES Consortium, Inc. (http://www.nees.org) to facilitate innovative products and construction techniques. This project has applicability not only within earthquake engineering but also to multi-hazards (e.g., hurricane science and engineering).

这个用于地震工程模拟研究的小额赠款研究网络(NEESR)有效载荷项目将利用美国国家科学基金会资助的项目(CMMI-0530759)的实验测试装置，该项目名为“NEESR SG：开发基于性能的海啸工程，PbTe”，于2007年6月至12月在俄勒冈州立大学NEES海啸波盆地进行。该有效载荷项目的目标是安装比海浪盆地另一边的SG研究人员测试的中高层建筑更大规模的住宅结构模型，以调查波浪加载和抬高(应用于海啸工程)和压力/风力驱动的涌浪(应用于飓风工程和科学)造成的影响。有效载荷项目将在水线上方的平面上安装两个单户住宅模型，这些模型代表沿海地产或略有内陆的结构。这个有效载荷项目将产生以下新知识：(1)关于住宅结构上流体冲击载荷随不同波高和地面坡度的函数的信息，以便于开发供从业者/规划者使用的无量纲图表，并促进沿海地区创新的施工技术；(2)了解波浪和浪涌载荷下住宅结构上的载荷传递机制和上升力，这两者目前尚不清楚；以及(3)通过现有方法、公式和最小组装试验，缩尺模型压力与全尺寸原型破坏的关系。因此，将产生关于木结构结构在海啸载荷下的反应的新信息，并向地震工程界和更广泛的科学界提供。更广泛的影响：实验结果将通过NEES联合会(http://www.nees.org))运营的NEES中央数据库向研究人员、从业者、设计师和公共政策官员提供，以促进创新产品和建筑技术。该项目不仅适用于地震工程，而且适用于多种灾害(如飓风科学和工程)。
