Fort McCoy, Wisconsin Building 550 maintenance plan

Building 550 (former World War II fire station) is located on Fort McCoy, Wisconsin, and was recommended eligible for the National Register of Historic Places (NRHP) in 2018 (Smith and Adams 2018). The building is currently vacant. It is an intact example of an 800 Series World War II fire station with character-defining features of its period of significance from 1939 to 1946 on its exterior and interior. All buildings, especially historic ones, require regular planned maintenance and repair. The most notable cause of historic building element failure and/or decay is not the fact that the historic building is old, but rather it is caused by incorrect or inappropriate repair and/or basic neglect of the historic building fabric. This document is a maintenance manual compiled with as-is conditions of construction materials of Building 550. The Secretary of Interior Guidelines on rehabilitation and repair per material are discussed to provide the cultural resources manager at Fort McCoy a guide to maintain this historic building. This report satisfies Section 110 of the National Historic Preservation Act (NHPA) of 1966 as amended and will help the Fort McCoy Cultural Resources Management office to manage this historic building.

Finite Element Failure Analysis of GFRP Laminates in Plate-Cone Reticulated Shell

Plate-cone reticulated shell is a new type of spatial structures with good mechanical behavior, technical economy, and architectural appearance. In this paper, using ANSYS software, the strength failure analysis model of composite laminates is established in cooperation with the Strength Criterion of Hoffman. The effects of layer number, laying direction, and thickness of laminates on the ultimate strength of laminates are studied by detailed parametric analysis, which provides a theoretical basis for the design of composite plate-cone reticulated shell and GFRP laminated plates. Some important conclusions are obtained and can be applied to engineering practice.
