FINITE ELEMENT ANALYSIS OF PERFORMANCE OF MULTI-RIBBED COMPOSITE WALL SUBJECTED TO VERTICAL LOAD

Utilizing finite element method,it is made the performance analysis of contribution of in-filled block in composite wall to anti-compression,distribution feature and law of axial force under vertical load.Using cross-section shape and size of frame column and ribbed-column,arrangement of ribbed-column and height of blind beam as parameters,the influencing factors of distribution coefficient of axial force are discussed and its calculation value is given,it provides a basis for calculating axial force of frame column and ribbed-column.
