For this problem, you are to use the two-dimensional frame analysis program you wrote during the semester to solve the following problem. The building in Figure 4 is a simple model for a light industrial building. The second and third stories are loaded uniformly, the roof is unloaded. Since this is a steel frame, we will ignore self-weight. Along the side at the roof and each floor level are applied point loads representing an environmental load, say wind loading. The horizontal beams are W12x26 members, orineted so the strong axis is in bending under the applied gravity loads. Your job is to perform an analysis to determine the wind load that will first yield any of the sections. This would be the beginning of a push-over analysis, as described in class. 1. Assume the columns are W12x14, oriented so the strong axis is in bending. Apply a scale factor to the wind loads proportionately to determine first yield
