i do not see any specific thing in that it should be designed as normal industrial structure.
The concrete footing should be designed correspoding to the forces as per ur analysis wind or whatever itmay be. The manufacturer will give the base forces to u for the design of the footing.
Once u...
sizing of the splice plate will be based on no. of bolts to be acommodated to transfer the shear it will be further depend on the how u are providing the bolts the most preferred way in tower is the staggering arrangement of the bolts.
the plate size than must be checked for bearing and tearing...
as long as the system has to bear only wind load further sice the building is just 1 story the magnitude of the wind loading is very low which in general should not afffect the system as u planned and it must be ok if designed properly but definitly it will not act as desired under seismic...
i agree to lutfi i m not sure if u can really reduce the live load just for four stories.if allowed in ur code than u have to see the load combinations under which the reduction is permitted.i think for dynamic analysis this reduction is not existing

There is now such specific provision for underground structure in general it is found that earthquake forces are not critical for the underground structure provided the plan layout of the building is symmetrical and also fitting in to the aspect ratio criterion .
however for analysis u can...
a better option may be that u can provide a subfloor drainage system as the mass of the building is less than the water pressure than it is really a problem for the building u have to exploe a potential system for drainage below the building and this subfloor drainage system u can laid atleast...
THE APPROACH OF JAE FOR THE DESIGN OF SUCH SYSTEM IS ABSOLUTELY PERFECT.

every structures is having it's own natural freauency depending on its structural configurations like plan and in particular the height of the building the calculations for the natural frequency for rough idea is very simple but for actula analysis you need to have a proper modelling and...
IN GENERAL IT IS FOUND THAT CLASS 1 TMBER LAGGING CAN LAST TILL 6 TO 7 YEARS UNDR WET CONDITIONS BUT IT'S PERFOMRMANCE GETS DETERIORATED BECUASE OF CORROSIVE ATMOSPHERE FURTHER IT WILL DEPEND ON THE SALT CONTENT OF THE WATER AS WELL.
BUT A STUDY SUGGESTS LEAVING THE WEEP HOLES THROUGH THE...
