同时试验现象也表明，楼板在协调相邻两榀桁架共同工作时起了重要的作用，其水平剪力在楼板中的传递是通过楼板中的拉力场来实现。
Moreover, it is the floor that makes the two neighboring trusses work together, and the horizontal shear forces are transferred by the tension field within it.
空间桁架模型理论认为，承台内部力流是沿桩柱间的空间桁架传递的。
The space truss model theory argues that the stress flow transfers along with the truss composed of piles and column.
