Space purlin design results and inadequacies of steel joists are displayed in the Steel Joists dialog. The diagonals dialog displays the axial compressive strength ratio, slenderness control, and design ratio.
Location of the Steel Joists Dialog
After the analysis is done, you can access it by clicking the Steel Joist command under the Steel Design heading in the ribbon menu Analysis and Design tab .
Space Purlin
Specifications |
|---|
ID  It is the name of the space purlins in the plan. |
Section  It is the section used in space purlin elements. |
Material  It is the material used in space purlin elements. |
Combination  It is the load combination that produces the most unfavorable axial capacity ratio. |
Pr  It is the largest axial force calculated by using load coefficients among the elements forming the space purlins. |
Pn/Omega  Among the elements forming the space purlins, the most negative is the safe axial strength. |
Ratio  It is the axial capacity ratio. |
Strength check  It is an information box whose sign changes according to the presence or absence of negativity in the section. |
Slenderness  It is the delicacy value of the space purlin elements. |
Limit value  The maximum permitted slenderness of the space purlin elements. |
Slenderness check  It is an information box whose sign changes according to whether the delicacy limit is exceeded or not. |
Previous  The cursor moves to the previous line. |
Next  The cursor goes to the next line. |
OK  It saves the changes made and closes the dialog. |
