| Abstract: | The stress state of the semi rigid nodes at supports in the steel concrete composite structure is a big issue for the structural designers. The objective of the present investigation is to solve this problem through monitoring and analyzing the stress state during design and construction period for a practical engineering project with a long-span bidirectional steel-concrete shape composite beam. Through the comparison of different structural schemes for the same structure, it is proved that the long-span bidirectional steel concrete shape composite beam structure is a kind of low-carbon green structure which is suitable for sustainable development. |
