  4. 4. MODELING STATIC LOADS in GTSTRUDL<br />Independent Static Loadings<br />SELF WEIGHT LOADING Command (Section 9.4.1.1, Analysis Guide)<br />SELF WEIGHT LOAD ‘SW’ ‘SELF WEIGHT’ DIRECTION –Y ALL MEMBERS<br />Computed during the Stiffness Analysis process.<br />For immediate computation use <br />
  5. 5. MODELING STATIC LOADS in GTSTRUDL<br />Independent Static Loadings<br />LOADING Command (Section 9.3, Analysis Guide)<br />LOADING 1 ‘MACHINE LOADS’<br />Creates a new Independent Static Loading Condition, which will contain a set of Applied Static Loading Types<br />Use CHANGES mode to Add, Modify, or to Delete Applied Static Loading Types.<br />Use DELETIONS mode to remove an entire Static Loading Condition<br />
  6. 6. MODELING STATIC LOADS in GTSTRUDL<br />Applied Static Loading Types<br />JOINT LOADS Command (Section 9.5, Analysis Guide)<br />JOINT LOADS<br /> 1 TO 11 BY 2 FORCE Y 5.3 Z -9.1<br /> 250 ‘ABC’ ‘JT-13’ FORCE Z 19.8 MOMENT X 10.0<br />To add, or modify use the CHANGES mode of the LOADING Command.<br />
  7. 7. MODELING STATIC LOADS in GTSTRUDL<br />Applied Static Loading Types<br />JOINT DISPLACEMENTS Command (Section 9.6, Analysis Guide)<br />JOINT DISPLACEMENTS<br /> 1 5 7 19 DISPLACEMENT Y -1.5<br /> 250 ‘ABC’ ‘JT-13’ DISPL X 1.4 Y -0.5 ROTZ 3.5<br />To add, or modify use the CHANGES mode of the LOADING Command.<br />
  8. 8. MODELING STATIC LOADS in GTSTRUDL<br />Applied Static Loading Types<br />MEMBER LOADS Command (Section 9.7, Analysis Guide)<br />MEMBER LOADS<br /> 10 TO 20 MOMENT Z CONC FR M -25 L 0.3<br /> 1 TO 5 FORCE X GLOBAL UNIFORM FR W -1.2 / W -2.0 LA 0.0 LB 0.5<br /> 5 TO 9 FORCE Y LINEAR WA -1.0 WB -0.5 LA 0.2 LB 3.5<br />
  9. 9. MODELING STATIC LOADS in GTSTRUDL<br />Applied Static Loading Types<br />MEMBER TEMPERATURE LOAD Command <br /> (Section 9.8, Analysis Guide)<br />MEMBER TEMPERATURE LOADS<br /> 10 TO 20 AXIAL 30<br /> 1 TO 5 AXIAL 20 BENDING Z 20<br />
  10. 10. MODELING STATIC LOADS in GTSTRUDL<br />Applied Static Loading Types<br />MEMBER DISTORTIONS Command (Section 9.9, Analysis Guide)<br />MEMBER DISTORTIONS<br /> ‘B1’ ‘B2’ CONCENTRATED FR L 1.0 DISPLACEMENT X -1.5<br />
