基本应力理论 CAESAR II 的实施 Occasional Load Case Setup The “W + P1 + WIND” case will work for “linear” systems only. For “non-linear” systems, this is not sufficient, for the same reason “T1” is not sufficient for the EXPansion load case. The best way to setup OCCasional load cases is: (1) W + P1 + T1 (OPE) (2) W + P1 + T1 + WIND (OPE) (3) W + P1 (SUS) (4) DS1 - DS3 (EXP) (5) DS2 - DS1 (OPE) (6) ST5 + ST3 (OCC) 基本应力理论 CAESAR II 的实施 Occasional Load Case Setup (1) W + P1 + T1 (OPE) (2) W + P1 + T1 + WIND (OPE) (3) W + P1 (SUS) (4) DS1 - DS3 (EXP) (5) DS2 - DS1 (OPE) (6) ST5 + ST3 (OCC) This is the normal OPErating case This is a combined OPErating case which includes the OCC loads This is the standard SUStained case This is the standard EXPansion case This difference yields the effects of the OCCasional load on the system. This is not a code case, only a construction case, therefore (OPE). This handles non-linearities. This is our OCCasional code compliance case, stresses from Primary plus Occasional loads. 基本应力理论 CAESAR II 的实施 Load Case Generation Maintenance CAESAR II will recommend load cases for “new” jobs. By “new” jobs, we mean jobs that do not have a “._J” file. For “old” jobs, having a “._J” file, CAESAR II reads in the defined load cases and presents them to the user. The load case editing screen is shown at the right. 基本应力理论 CAESAR II 的实施 Load Case Generation Maintenance CAESAR II will recommend load cases for “new” jobs.
