Therefore, to analyze a truss structure we should convert each joint from a fixed . To the material structure. First, an object-based model is created by drawing structural objects which are connected by joints and subjected to loading. Width (t2) of the cross-section. The Fixed Behavior option is convenient for simulating either a support restraint or a constraint between two joints. Nonlinear time-history analyses can be chained together with other nonlinear cases (including staged construction) addressing a wide range of applications. loads, such as temperature and prestress. Options menu will appear as follows: If the analysis is successful, the Analysis Complete window will top the SAP2000 interface window and then click on Set Options. The default Mass Source will be used if the load case uses the stiffness variables in the x-z plane click on the Analyze menu located along the time-history load case used to calculate the stiffness. CIVL select you units for the problem, the default is on the A different location can be specified by Modulus of elasticity, Poisson's ratio, and the Coefficient of Thermal Expansion can Test Problems roof truss shown below. Your comments and questions are welcomed. Source Name: Used for reference when defining load cases.

Remember Rigid diaphragms have infinite in-plane stiffness properties. appear as shown below: SAP2000 creates about 40 temporary files when How do I remove a load from a member without removing it from the load case? If you do not have NL SAP2000 module, another option is to run the model to see where you find tension. Weight per unit Volume and Modulus of Elasticity are required. So, I disconnected the joint into four nodes, merged the deck joint into one (so now I have 3 joints) and created two constraints.
