Gantry girder
Gantry girder or crane girder hand operated or electrically operated overhead cranes in industrial building such as factories, workshops, steel works, etc. to lift heavy materials, equipment etc. and carry them from one location to other , within the building
The GANTRY GIRDER spans between brackets attached to columns, which may either be of steel or reinforced concrete. Thus the span of gantry girder is equal to centre to centre spacing of columns. The rails are mounted on gantry girders.
Loads acting on gantry girder
Gantry girder, having no lateral support in its length (laterally unsupported) has to withstand the following loads:
1. Vertical loads from crane :
Self weight of crane girder
Hook load
Weight of crab (trolley)
2. Impact load from crane :
As the load is lifted using the crane hook and moved from one place to another, and released at the required place, an impact is felt on the gantry girder.
3. Longitudinal horizontal force (Drag force) :
This is caused due to the starting and stopping of the crane girder moving over the crane rails, as the crane girder moves longitudinally, i.e. in the direction of gantry girder.
This force is also known as braking force, or drag force.
This force is taken equal to 5% of the static wheel loads for EOT or hand operated cranes.
4. Lateral load (Surge load) :
Lateral forces are caused due to sudden starting or stopping of the crab when moving over the crane girder.
Lateral forces are also caused when the crane is dragging weights across the' floor of the shop.
Types of gantry girders
Depending upon the span and crane capacity, there can be many forms of gantry girders. Some commonly used forms are shows in fig .
Rolled steel beams with or without plates, channels or angles are normally used for spans up to 8m and for cranes up to 50kN capacity.
Plate girder are suitable up to span 6 to 10 m.
Plate girder with channels, angles, etc. can be used for spans more than 10m
Box girder are used foe spans more than 12m.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Design of Simple Shear Connections
(Bearing type connection)
Strength of bolts is governed by;
1- Shear failure of bolts
φ Rn = 0.75 . Fv . Ab . Nb . Ns
Where;
Fv : Shear strength of bolts
(for A325 bolts = 400 MPa)
Ab : gross area of bolt
Nb : Number of bolts
Ns : Number of shear planes,
For group A, Ns = 2, for group B Ns= 1
2- Bearing failure of plate
φ Rn = 0.75 * 2.4 Fu (d . tmin) . Nb
Where:
Fu : ultimate tensile strength of plates
d : diameter of bolts
tmin : of group A bolts is less of tw or 2tangle
of group B tflange of column or tangle

Example
Solution:
Check the shear strength at critical section
For W 480 x 473, h/tw = 756 / 26.4 = 28.6 < 2.45 2 x 105
= 69
250
∴ φVn = 0.9 x 0.6 Fy . Aw where Aw = (690 + 48 ) x 26.4 = 19483 mm2
φVn = 0.9 x 0.6 x 250 x 19483 x 10-3
= 2630 > Vu = 1000 kN ∴ OK
Strength of Bolts
a) Group (A) bolts (Double Shear)
1- Shear Failure, φ Rn = 0.75 x (πd2
/4) x 400 x Nb x 2 = Vu = 1000 x 103
∴ d2
Nb = 2122.07
Try , if
Nb d (mm) Spacing = 690/Nb
3 26.5 230mm = 8.67 d > 6d not OK
4 23 172 mm = 7.5 d > 6d not OK
5 20.6 138 mm = 6.7 d > 6d not OK
6 18.8 115 mm =6.1 d > 6d not OK
7 17.4 98.5mm = 5.6 d < 6d O.K
Determine the number of bolts
needed to support an ultimate

W 840 x 473 to a main beam
W 920 x 653 with double
angles 65 x 65 with a length of

F v for bolts = 400 MPa
Fu for steel = 400 MPa
Fy for steel = 250 MPa
For W 840 x 473
d= 893 mm
h = 756 mm
tw = 26.4 mm
tf = 48 mm
For W 920 x 653
d = 972 mm

2- Check bearing strength for 7 M18 bolts
φ Rn = 0.75 x 2.4 Fu x d x tmin x Nb
= 0.75 x 2.4 x 400 x 18 x t min x 7 = 1000 x 103
∴ t min = 11.02 = 2 t angle
∴ tmin of angle = 5.5 mm
∴ Choose double angles 65 x 65 x 6.35 mm
b) Group (B) bolts (Single Shear)
1- Check Shear Failure,
φ Rn = 0.75 x (π 18 2
/4) x 400 x 14 x 1 x 10-3
= 1068.8 kN > Vu = 1000 kN
2- Check bearing strength
φ Rn = = 0.75 x 2.4 x 400 x 18 x 6.35 x 14 x 10-3
= 1152 kN > 1000 kN
Check shear block of double angles
D hole = 18 + 3 = 21 mm
Lv = 6.5 s = 6.5 x 98.5 = 640.25 mm
Av= 640.25 x 2 x 6.35 = 8131.2 mm2
Avn = 8131.2 – (6.5 x 21 x 6.35 x 2) = 6397.65 mm2
Gage distance g = 35 mm , Lt = 65 - 35 = 30 mm
Atg = 30 x 6.35 x 2 = 381 mm2
Atn = 381 – 0.5 x 21 x 6.35 x 2 = 247.65 mm2
0.6 Fu Avn = 0.6 x 400 x 6397.65 x 10-3
= 1535.44 kN
Fu Atn = 400 x 247.65 = 99.06 kN
0.6 Fu Avn > Fu Atn
φ Rn = 0.75 [0.6 Fu Avn + Fy Atg]
φ Rn = 0.75 [ 1535.4 + 250 x 381 x 10-3
] = 1223 kN > Vu = 1000 kN
∴ Choose 7 bolts with
diameter 18 mm with
spacing = 98.5 mm for
group A
∴ Use 14 M18 for group B bolts
∴ double angles 65 x 65 x 6.35 mm with 7 M 18 A325 bolts with spacing 98.5 mm
and gage distance g = 35 mm are sufficient to resist Vu = 1000 kN
