Pad Foundation and Load Take Down

Test coming up about  this topic

Section Properties

Section Properties

Section Properties are extremely useful when trying to determine section capacities:

Given the relationship of M/I = Sigma/y

I is useful and is the second moment of area: Which reflects the how points are distributed with regard to an arbitrary axis.



Ixx = bd^3/12 + Ah^2


Ie Sum of Ixx = Sum of Ixx + Sum of A(y*bar-y)^2

or

Iyy = Sum of Iyy + Sum of A(x*bar - x)^2

Use of the parallel axis theorem to find second moment area of an axis.

Quarterly Report

My target as set for work is to produce a quarterly report for the end of July ( 31st July).

In order to do this I am going to set out some of the things prerequisite for the quarterly report.

 

Joy Global Bucks Bridge Contract – has been worked on

Attended meeting for Kings Cross Bridge Structure

Blackwall Tunnel Roof Metal Motor Design Project

Solve Model been down for the design

COC1033a Bridge Project – Load Take Down for this

Load Capacity worked out for various components of COC1033a Bridge Project

Balfour Beatty Rail – 001 Thameslink K02 - London Bridge Gantry Project Inspection of Bridge Organised – Gap Analysis and Created Solve Model for the following Project -

Tensile Capacity of a Screw worked out

CrossRail  - Havier

Rail Project to be done on this project - Dilesh

 

 

For the Joy Global contract, I was assigned to perform a Cat xx check on the Bridge project – since this was my first assignment and no specific procedure had been given to follow the aim of the exercise was to follow the procedure as per the guidelines. To apply the works accordingly and try to come up with a relevant procedure as needed for the works.

 

Historical drawings were used to check the initial assumptions of the project as required. 1) Thing such as the skew of the bridge ie at 20 degrees was verified. The dimensions of the individual elements. The main factor here was the conversion from feet – centimetres (imperial to metric) conversion was used here to ensure that verification of the members.

 

Initial assumptions were checked for the structure to check the calculations in the excel spreadsheet were done accordingly.  One of the factors was to use a short method to check things such as the maximum bending moment of the structure.

 

Load Path to be checked of the structure

Dimensions verified

Assumptions checked ( skew of bridge)

Live Loading ( As per client demands)

Design Codes used and went through to clarify the structure and what is needed to be done

Some truck loadings were non-standard

BS EN 1993-1-1 Eurocode - Structural Steel

I have been having trouble trying to interpret this Design Code so I have broken it down into essentials:

1) When my manage says find the Section Capacity it means examine the section properties: ie 2nd Moment of Area, Yield Stress of Material to deduce what would be the maximum design load it can carry etc:

2) Then when it says applied loading it means check.actual.load then derive the utilisation ratio.
