This document outlines the structural analysis of a tower, including definitions of loads, materials, and calculations for various plans and elevations of the tower structure. Sections are dedicated to modeling planes, loads, frame checks, and bolted joint analyses for the tower plans at various heights as well as the furnace, alignments, stairs, and railway components. Frame elements and connections are checked under the defined loading conditions.
The zombie invasion has proven too much for humanity and as such we must move on to the moon and eventually to Mars. In preparation for this trip space shuttles must be constructed at depots around the world. The WGTG Corporation has been formed to accomplish this task.
The depots require an integrated system to run the manufacturing process. To meet this need the ShipDepot application stack has been developed. ShipDepot is a three-tier application designed to run in Docker containers to provide the upmost resiliency as any interruption in service will no doubt cost human lives.

4.1 DEAD LOAD (DEAD)
All the self weight of he members have been multiplied by 1.2 to take in account the weight of plates, bolts,,,
The self weight of the covering plates is: 0.45 kN/m²
The self weight of the handrails has been judged negligible.
4.2 LIVE LOAD (LIVE)
The design live load is 4.0 kN/m². This load has been applied only in the areas equipment free.
4.3 EQUIPMENT (EQPT_SL,EQPT_DX_X,EQPT_DY_Y)
The equipment is formed by the elements of the furnace and other various equipment.
In particular the EQPT_ST is due to the equipment of rolling, coil and other equipment.
The EQPT_DX_X-EQPT_DY_Y are due to the dynamic load of fan coil.
The loads are taken by _________________ report in the following.

From roll 2 Eccentricity: 1.15 m My = -91,94x1.15 = 105,8 kNm
From roll 4 Eccentricity: 1.65 m My = -50x1.65 = -82,5 kNm
From roll 5 Eccentricity: 1.65 m My = 50x1.65 = 82,5 kNm

From roll 7 Eccentricity: 2.5 m My = -50x2,5 = -125 kNm
From roll 8 Eccentricity: 2.5 m My = 50x2,5 = 125 kNm
From roll 9 Eccentricity: 1.25 m My = -50x1.25 = -63 kNm
From roll 10 Eccentricity: 1.25 m My = 50x1.25 = 63 kNm
The maintenance load is the suspended loads of the monorails (15-30-20 kN).
The railway present in rows B1-C1 is used by minispangle (tag load 440 kN) active in operating condition
and by crane (tag load 270 kN) active in maintenance condition.
Conservatively this load is applied as moving load in all support points of the monorails/railway.

4.6 OPERX / OPERY
Below the furnace level there are the support of the strip.
These support are sustained by longitudinal beams between the main columns.
