1 SE 103 Conceptual Design University of California, San Diego SAP 2000 (version 14) 2D Introductory Tutorial 2D Truss SAP2000 Introduction The purpose of this tutorial is to introduce Structural Engineering students to some of the capabilities of Structural Analysis Program (SAP2000). Throughout the rest of your stay at UCSD other classes will require you to use SAP2000 and this class will prepare you to become comfortable with the program to increase your usage of it later on. This program and variations of it is also widely used in industry and becoming familiar with it will greatly increase your marketability to a company someday. It is an excellent tool to aid in modeling, analyzing, and designing structural systems. Whereas SolidWorks is useful in modeling individual members, SAP2000 is useful in modeling many members much faster than SolidWorks. A brief description of the program, as described by the developers, can be seen below: SAP2000 is a stand-alone finite-element-based structural program for the analysis and design of civil structures. It offers an intuitive, yet powerful user interface with many tools to aid in the quick and accurate construction of models, along with the sophisticated analytical techniques needed to do the most complex projects. SAP2000 is object based, meaning that the models are created with members that represent the physical reality. A beam with multiple members framing into it is created as a single object, just as it exists in the real world, and the subdividing needed to ensure that connectivity exists with the other members is handled internally by the program. Results for analysis and design are reported for the overall object, and not for each sub-element that makes up the object, providing information that is both easier to interpret and more consistent with the physical structure. Key Point: SAP2000, and other analysis programs like it, are not to be used in place of hand calculations or relied upon blindly. Their purpose is to VERIFY design and hand calculations. One other important concept to understand about SAP2000 is its assumption on joint connectivity. SAP2000 as you will see, assumes ideal connections meaning it is either completely rigid or completely pinned. In the real world this usually is not the case and something to keep in mind when comparing results between SAP2000 and an actual physical model. If this doesn’t make sense now, it should as you go through the tutorial. Tutorial Overview Upon completion of this tutorial, students should be comfortable with using SAP2000 for 2D models and should be able to model and analyze the truss for Lab Assignment 1.
