New Yurt build

[rodney757]

Hello,

My wife and I are beginning to build a 24' yurt that we will live in for the next few years. We are building the platform for our yurt and I have a question regarding the load capacity. We are following the 24' Pacific

Yurt platform

plans (http://www.yurts.com/images/media/24...form_plans.pdf) and it calls for laying 2x6 T&G directly on the 4x6 beams.

We are actually using sistered 2x8s for the beams. I have looked online, and am having a hard time determine the maximum load for the 2x6 decking if the beams are 4' OC. I am trying to determine if we should add blocking in-between the beams or not.

We are thinking of putting an earthen floor ontop of the decking which would weigh around 3000lbs. Will the decking be able to support this? What is the maximum load for the 2x6 decking with "joists/beams" 4' OC?
