autocad drawings of precast concrete cladding panels for - NEES

ContributionsCladding panels were a new addition to the study of this five story reinforced concretebuilding to test the connections of the panels to the building. In addition, a fire test willbe completed after the earthquake test to examine how easily the fire will spread fromfloor to floor with the addition of the cladding panels.The NEES REU students on this project worked closely with Professors TaraHutchinson and Kurt McMullin to develop a proposal for funding for the claddingsystems. Two REU students were from UC San Diego who focused on the analysis ofthe cladding panels and ordering cladding supplies. The other two students were fromSan Jose State University and helped prepared detailed drawings of the claddingpanels and their connections for the supplier. Professor Kurt McMullin emailed handsketched drawings and called via phone to discuss how everything should look. Theteam provided him AutoCAD drawings based on his descriptions. Over the summer, theteam was able to produce approximately 80 different drawings.AutoCADEach week on Tuesday and Friday, the REU team from San Jose State had deadlinesto provide new and most updated AutoCAD drawings for Tara Hutchinson and KurtMcMullin. The importance of this was to ensure that when they had their meetings withthe Precast Concrete Institute (PCI), they had drawings to support their proposal.Although 80 drawings were completed, this paper focuses on six: an elevation view, afloor plan, an angle embedment plate, and three detail drawings of the installation of theembedment plates, a concrete panel, and the connect to the beam with the panel.Four different elevation views were needed for the building to show where and whattype of cladding panels will be needed. Figure 4 shows the south view of the buildingand all the panels that will be used. Each panel is labeled to indicate the different typesof panels that are needed. Spandrel Panel 1 (SP-1) will be used for the covering upmost of the slab edges. Spandrel Panel Returns (SR-1) will also be used to cover theslabs near the corners in addition to columns A and C. They are U-shaped panels andare mainly on the west and east views. Column Cover Long (CL-1) is placed to hidecolumn B while Column Cover Short (CS-1) is placed to hide half of the columns A andC. Column Cover Returns (CR-1) are L-shape panels that are wrapped around thecolumns A and C. When panels meet in between columns, a 2-inch seismic gap isneeded.4 | P a g e
