| Abstract: | The temperature field and inner force of concrete-filled steel tubular(CFST) rib subjected to cement hydration heat during its growth is calculated by using general finite element program.When the concrete is constructed in different temperature,the temperature fields and the inner force of the concrete-filled steel tubular rib are different. |
| |
| Keywords: | concrete-filled steel tubular rib growth cement hydration heat temperature field inner force remain due to temperature |
