P-Delta Analysis

All analysis cases have been solved in the following way:

Similarly for the other cases.

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.

4.4 QUAKE_X-Y

For the definition of the seismic force it is used Seismic design code for Dubai (2013) with input data

Ssd/g=0,24; S1d/g=0,16.

4.5 OPERATING LOAD (COIL)From the Tension Diagram produced by Danieli, the strip tension is 50,0 kN.

IMMAGINE IS NOT AVAILABLE


Rev. 0

In the hot bridle area we have to consider the effects of the tension in the strip

Now we define the resultant forces on the roll axis.

The tension load on the strip is 50 kN

Moments:

From roll 1. Eccentricity: 0.85 m My = 68,04x0.85 = 58,3 kNm

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.

4.7 CONTENT (CONTENT)

It is the weight of content of silos present to height +15,5 pair to 18,4kN

4.8 MOVING LOAD (POT CRANE, MANUT RAILS, INGOT RAIL, MINISPANGLE )

Moving load are present in operating/maintenance condition. They are show in chapter [9].
