![]() ![]() In each Load Case Creat the Nodal Loads on truss as specified before.Make sure of the direction of forces acording to global coordinatesĪfter Creating the commond of (Perform AnalysisCheck) We have to assign the members that want to be this type of analysis for it. + 1.5 L.L + 0.8 W.L.Īnd In Dead Load Create the Self weight as For example, we can create a load combination 1.25 D.L. 2 and Wind Load is the Case No.3Īlso, we can define load combinations according to required. Then, we will be assigning them to the respective members/nodesįor example Dead Load Case can be Load Case No.1 ![]() First, we will be creating all 3-load cases. Defining Loads The creation and assignment of load cases involves the following two steps:ġ. Use the mouse and click on the nodes according to its support type as shown belowĤ. Using The Canadian Steel Tables All Top and Bot chords are one size L 55*55*3 All Diagonals and verticals are one sizeL 45 * 45* 3Īssigning the sections created to the modelīy clicking on the support icon the shown window will appear. E, density, etc.) Assume Preliminary Sections: In which we can define the material properties (ex. In which we can define the applied loads, load cases, load combinations. In which we can define the supports properties (restraints). In which we can define or choose members’ specifications. Property In which we can define or choose sections properties of the members of the truss. Node and beam labels are a way of identifying the entities we have drawn on the screen, and very useful when dealing with the output results How to see Diagram Labels(Nodes Numbers,Beam Numbers etc) of construction lines is excluding Ist line.Īfter clicking Snap Node/Beam ,use the mouse and connect between nodes created at the intersections of construction lines One of the methods that you can construction lines and then draw on these lines the truss members Noting that the no. The staad Graphical interface will appear as shown in below picture How to Start Staad Pro The Pic below shows how to start Staad Pro ![]() Note :To see the image clearly click the image. Main Steps Of Modeling Truss in STAAD PRO Īssigning Loads(Load Cases and combination)ĭefining Pre-Analysis Print out,analysis type and Post-Analysis print out Use all the data you take in steel course to design and analyze steel truss. The above figure shows a truss from several truss supposed to cover certain area.As shown the truss has a cantilever part ,its span equals 4 meters.The proposed truss depth is 3 m.The loads are shown as concentrated on tuss joints.The values of its load case are shown. For section 3.Design and Analysis of Truss Using Staad Pro Analysis and Design of Truss using Staad Pro It is therefore strongly recommended that until at least one year's experience of continually using STAAD is obtained, and for important structures, parallel hand calculations for the analysis and design of the structure be done as well.įor section 1.0 it is presumed that the reader understands Structural Theory and the Stiffness Matrix Method of Structural Analysis.įor section 2.0 it is presumed that the reader understands the fundamentals of Plate Theory, and the Finite Element Method based on the stiffness formulation. (4): Dependence on software can reduce the engineer's intuition of the actual behavior of the structure. (3): Computer programs usually have bugs. (2): The procedures used in programs are not transparent to the user. (1): The results are only as good as the modeling of the structure in terms of load effects representation, effective structural systems, the connection behavior, and the material idealizations. It must be mentioned however that since STAAD is a computer program, blind faith should not be placed in STAAD or any other engineering program. The following is a description of fundamental considerations for the effective use of STAAD-PRO for the analysis of structures. ![]()
