Sap 2000 demo11/5/2022 ![]() Press Load model data to load the model data, including the Groups and the available Sections. If not, the model will be loaded in the active instance of SAP2000. If SAP2000 is not currently running, it will be launched and the model will be loaded. A standard dialog box appears for the selection of the SAP2000 model file (*.sdb). SAP 2000 DEMO HOW TOThis spreadsheet is not meant to be an optimization tool that works out-of-the-box, but rather a demonstration of how to implement a link with applications that offer API.Ĭlick Open SAP model.This may not be suitable for all cases, in which case proper modifications must be made in the VBA code. The objective to be maximized is the sum of capacity ratios, with appropriate penalty functions which are applied when the capacity ratio is more than 95%, or when errors or warnings are returned from SAP2000.Minor changes are needed to work with newer versions. The worksheet is set up to work with version 19 of SAP2000.This is not a restriction, but minor changes in the worksheet and SAP2000 model need to be done for other configurations. The test model provided herein is a toy model of a steel structure and the design is meant to be carried out according to EuroCode 3.This can be easily increased in the worksheet, and more groups can be taken into account with the professional edition of xlOptimizer. A maximum number of 10 groups is set up within the worksheet, which is consistent with the restrictions of the demo version of xlOptimizer (up to 10 variables).It can be used for any structural model created by SAP2000. We have already created the spreadsheet for you. xlOptimizer will pick the optimum section for each one of these groups. Also, the frame members are grouped into meaningful Groups e.g., corner columns, exterior columns, interior columns, beams, x-braces, etc. It is assumed that the structural model is complete and checked for errors (nodes, members, connectivity, supports, loads, design options, etc). Optimization with xlOptimizer allows for the selection of the optimum frame sections for each member group in the model. SAP 2000 DEMO FULLThis process is possible since SAP2000 exposes a full API (Application Programming Interface) which can be used by VBA. The purpose of this example is to demonstrate the use of the well-known CSi SAP2000 structural analysis program within Microsoft Excel and the optimization of a structure using xlOptimizer. ![]()
