Abstract

Abstract

To predict the lateral pressure of formwork more accurately, an experiment aims to investigate the influence on lateral pressure of formwork caused by the time-varying characteristics of friction coefficient μ and reduction coefficient K was conducted. Based on the method of stratified summation, a model for calculating the lateral pressure of formwork was established, the modified calculation formula was deduced and verified. The results showed that the modified formula that considering the time-varying characteristics of key coefficients could perform well in predicting the lateral pressure of formwork.
