INTRODUCTION
Foundation :
Membranestructure classify to be one type of structure that require engineer to design for, foundation. This chapter intend to give you a guide for determining the size and the steel reinforcement of footingsupporting the primary columns of membrane structure.
INTRODUCTION
1, the bearing capacity ( Kg/ cm2 ) of the soil which is the ability of the soil to resist applied loads 2. the columnsreactions (KN) of the membrane structure which are the loads transfer from the structure to the base of the columns. The column reaction will be provide in the reaction force report. This data can be used asa starting point for the design of foundations. But the construction of foundation must not start before the final anchor bolt plan is issued and verified against the data used in the design offoundation. The soil bearing capacity must be obtained through a specialist in soil investigation.
