2-D Frame with Static Loading
Description
This tutorial describes the modeling and analysis of a seven-story two-dimensional frame structure, subjected to static earthquake loads. The framing and the static loads are shown in Figure 1-1.

Building the Model in SAP2000
Using Templates
1. Select the units you want to work with from the status bar at the bottom of the SAP2000 window. In this case let’s start with Kip-ft.

Note: You can change the units you are working with at any time and SAP2000 will handle the conversion. 2. From the File menu select New Model from Template.3. 4.

Select 2D Frame. Fill in story and bay information. For now use 13 ft for story height and we will edit the first two floors and their grids next.

Editing Model
We are going to edit the framing and the grid at the same time. 1. From the Draw menu select Edit Grid. Hint: Always try to locate your joints at grid intersections. By providing grids you can make inputting, modifying and...
