Chongqing 400020 China) Abstract:Full hall formwork support was added in the new code.Stability calculation for upright stanchions of the support involves dividing the stanchion into top segment and bottom segment and their stabilities are calculated separately.Many coefficients have been adopted in the calculation.Through typical demonstrations the authors introduced the calculation length of full hall formwork support the stability check for upright stanchion calculation of the stability of upright stanchions by reducing the intervals.The authors also discussed on the use of the coefficients pared different types of full hall formwork supports when subjected to different loads.At last problems that should be concerned in mind were summarized and suggestions were made. Key words:scaffolds;supports;calculating coefficient...
