SAP2000 2D Truss Design

Truss is one of the most popular structural forms used by mankind. It is primarily characterized by saving in material, axial forces, pinned joints and versatility of materials that can be used to build a truss. There are numerous applications of trusses. Below you can download a step by step procedure for analysis of 2D truss in one of the most brilliant programs for structural engineering SAP2000.

D.L= 10K, L.L= 20K, FY = 36KSI, FY=58KSI.

Basic Steps STEPS:

• Unit = K-ft.

• New model 2d truss, sloped truss. Number of division = 3, length (division)=15, Height= 12ft,

• Option>preference > steel frame design, ALSC-LRFD-93.

• Define > material, steel, modify, fy=36 ksi, fy= 58ksi.

• Define > frame section, import angle. Add angles, add auto select insert – all angles.

• Define > load cases, add line load, self xple=0.

• Define > add default combo, select steel, convert.

• Select all members.

• Assign > frame > frame sections, select autos elect.

• Select joint.

• Assign > join load > forces, apply loads.

• Select all.

• Assign > frame > release > partial fixity.

• Design > steel > steel design combo, UDSR1, UDSR2.

• Design > steel > select design/check.

• Design > steel > verify analysis Vs designed section.

• If members changed, reanalyze structure till no change, then select max x-sections & apply to all membrane & analyze for economy purpose.

• Display > show forces> joint UDSR2. It gives joint reaction.

• Display > show forces/stresses > frame, axial. It gives member forces.
