The Effective Length of Columns in Unbraced Frames - AISC

of if-factors for columns in unbraced frames by some rational analysis, that is, a stability analysis. The elastic solutions that have been developed indicate that the buckling will always occur in a sidesway mode, as shown in Fig. la.1 The* buckling mode shown in Fig. lb, in which no sidesway occurs, is a more stable condition,

Chapter 7 - Underground Installation of PE Piping

In unbraced or unsupported excavations, proper attention should be paid to sloping the trench wall to a safe angle. Consult the local codes. All trench shoring and bracing must be kept above the pipe. (If this is not possible, consult the more detailed installation recommendations.) The length of open trench required
