Abstract

When a substantial torsional moment is present, the magnitude of the longitudinal stresses on the core walls due to warping and the header beam forces are quite significant and those actions are too large to be neglected. Many methods developed for warping analysis of concrete cores are either not applicable for complex core structures or difficult to adopt in normal design offices because they are not versatile enough for practical applications. Also, models based on either open sections or completely closed sections may be grossly inaccurate for partially-closed core sections. A simple method of analysis for estimating the longitudinal stresses on walls and header beam forces for torsional..
