THERMAL ANALYSIS AND DESIGN OF OVER-LONG HIGH-RISE CONCRETE BUILDINGS
This paper considers the effects of annual temperature changes on the response of a over-long high-rise building in Hangzhou,east of China.Several scenarios with varying assumptions of construction sequence,temperature conditions and material properties are considered.The thermally induced forces and deformations in structural members are computed using finite element analysis (ETABS).Various references were used to compute the demands on structural elements considering thermal loads,and shrinkage and creep,and to estimate the implications of those forces on the structure including prediction of frequency and size of cracking that may be expected and localized strengthening of certain areas in order to control cracking and/or improve strength resistance.Recommendations from those references were evaluated in conjunction with results from the structural analysis of the building.
