The terms "member" and "beam" are synonymous. - The use of the term "beam" should not be taken to imply that the member cannot resist an axial load. - Beam entities are used to model beams, columns, braces, etc. 3. **Plates** - Plates are finite elements commonly used to model "surface structures" such as walls, slabs, plates, or shells. - Plates may be either 3-noded (triangular) or 4-noded (quadrilateral). 4. **Solids** - Solids are finite elements that enable the solution of structural problems involving three-dimensional stresses. - They are useful for solving problems such as stress distribution in concrete dams, soil and rock strata, etc. - Solid elements typically consist of 8 nodes. - Solids most commonly take the form of cubes, but by collapsing various nodes together, an 8-noded solid element can degenerate into forms with 5 to 7 nodes. ## Performing the Analysis STAAD.Pro can perform various types of analyses on a structure and offers options for obtaining a printout of model information and the results of an analysis. 1. **Perform Analysis** - Instructs STAAD to perform a linear elastic (stiffness) analysis. 2. **P-Delta Analysis** - Performs a second-order elastic analysis that considers the effects of the applied loads acting on the displaced structure (P-∆ effect). - This type of analysis is generally preferred by most building codes. - This is an iterative analysis process. - This analysis type also has options to specify the number of iterations to be performed or to place a convergence tolerance on the displacements from successive iterations. - There is also an option to include the P-8 (small delta) effect, which considers the effect of applied loads acting on the deformed shape of individual members. - Finally, this analysis includes an option to include the Geometric Stiffness (Kg) matrix, which modifies the member stiffnesses based on the applied loads. 3. **Cable Analysis** - Performs a nonlinear cable analysis on a structure that contains nonlinear cable members. 4. **Direct Analysis** - Performs a Direct Analysis in accordance with Appendix 7 of AISC 360-05. - This method accounts for the second-order effects resulting from deformation in the structure due to applied loading, imperfections, and reduced bending stiffness of members due to the presence of axial loads. - This analysis is similar to a P-Delta Analysis with the Use Geometric Stiffness (Kg) and Small Delta options selected. - However, this analysis calculates modifications to the stiffness matrix using the to factors described in AISC 360-16. 5. **Pushover Analysis** - Performs a static, non-linear procedure in accordance with FEMA 356. - In this method, a lateral "push" load is applied to the structure and increased progressively according to a predefined loading pattern until either the loading or the structure displacement reaches a prescribed level. - This method considers the non-linear behavior of the structure, allowing plastic hinges to form in the structure until a collapse mechanism is created. - This technique is typically applied for the seismic rehabilitation of structures. 6. **Imperfection Analysis** - Considers the secondary effects of loads acting on members that have an initial curvature (camber) or an initial drift (out-of-plumbness). - This analysis is used on structures that have members with an imperfection specification applied to them. 7. **Buckling Analysis** - Identifies the factor by which the loads in the selected load case should be increased (or decreased if the factor is less than 1) such that Euler buckling first occurs in any member of the structure. 8. **Generate Floor Spectrum** - Used to request the calculation of floor and/or joint response spectra from time history results. - This is particularly useful in the analysis of floor systems supporting vibrating equipment. - This feature requires a license for the Advanced Analysis Engine.
