I was in the study of this problem, it should be the construction is not based on beam design has been explained, but the quota is a little different, the beam bottom cushion or other basis should be the beam, it should be suspended under the general frame or beam. The difference is that the two side support and the three side support. Usually the explanation is still looking for evidence.
The foundation beam without the beam side template of this code, the foundation beam is not calculated at the bottom of the template, select the basis of the beam on the beam directly to the template area.
