Detailed Solution
Download Solution PDFMaximum slenderness ratios for tension members:
|
Type of Member |
λ |
|
A tension member in which a reversal of direct stress occurs due to loads other than wind or seismic forces. |
180 |
|
A member normally acting as a tie in roof truss or a bracing system but subjected to a possible reversal of stresses resulting from the action of the wind or earthquake forces. |
350 |
|
Member always under tension |
400 |
Maximum slenderness ratios for compression members:
|
Type of Member |
λ |
|
A tension member in which a reversal of direct stress occurs due to loads other than wind or seismic forces. |
180 |
|
A member carrying compressive loads resulting from dead loads and imposed loads. |
180 |
|
A member subjected to compressive forces resulting only from combination with wind/earthquake actions, provided the deformation of such members does not adversely affect the stress in any part of the structure. |
250 |
|
Compression flange of a beam restrained against lateral-torsional buckling. |
300 |
|
A member normally acting as a tie in a roof truss or a bracing system not considered effective when subjected to a possible reversal of stresses resulting from the action of wind or earthquake forces. |
350 |
