Tower Crane Project

Yo. Im doing a project for college called " Truss tower crane design and the Structural Stability analysis". Im just posting here on the off chance that maybe there is someone knowledgable here, or knows about manufacturing them.

Well im finding a small bit of trouble with finding more specific information on them on the internet, and the library/databases i have access to arent that helpful (besides douwnloading the British Standards on how how to design BS2573- 1.

Where i could be helped in is how to decide what type of truss to use (i have specifications, but how to decide would help me), what type of crane to use for the job, etc.

I can elaborate some more in the more specific areas i need help if there is someone who might be knowledgable and willling to help me.

Thanks in advance

Skept

yea I'm 11 and have no clue

lol.you probably should have not posted at all....

atleast thanks for the attention. Just shows im noticeable :D

Here is what I googled:

Here's a stress image for a crane: http://www.apm.ru/imageseng/Structure3D/struct6.jpg

I'm not too sure if I'm just bothering you, or helping; but my dad is an engineer, so I could always ask him. The problem is, I don't know the question; maybe you could tell it, or at least tell what it is asking.

well ive googled it and done more research than just google, this is a pretty serious project and alot of my time over the months will be spent on it. But i was finding it hard to find info in certain areas/aspects of it. Any help would of course be grateful, whether helpful or not. 

My exact brief is as follows

Truss Tower crane design and structural stability analysis

This project concerns the design of a truss tower crane for a multi story building construction. The tower has a maximum height of 70m for the erection of a 20 story building with a 3m floor separation and is required to support a cross arm with a span of 20m for variable load handling using a drive motor hoist with counterbalance load stabilisation

The main objectives are to

1. examine various truss designs and specify a suitable space frame vertical structure with the necessary shape, height and cross arm span with counterbalance load.

1. perform a detailed analysis of the forces experienced due to (a) worst case vertical load handling during the building construction in the presence of thermal expansion in 50 degrees Celsius heat, and (b) effects of wind gusts at 150km/hr on both the tower and load hoist.

1. carry out a dynamic analysis of the crane forces during load lift.

Hey Bud, try the good old cit library site(http://library.cit.ie/). Theres a tab called "Online database" there, follow it (If your IN the library just pick "access on campus" and if its from yer house pick "off campus" n enter your student No. n should let you in) (http://library.cit.ie/screens/dual_databases.html) and then choose "Science direct" tab.. Just do a search there

I searched "Truss Tower crane design" and got 126 articles.. Prob most of them are useless but the 1 your looking for might be there...

Not sure if you knew about this but said I'd mention it anyway...

Be sure to keep the flux capacitor at 83% efficiency.

im pretty sure flux does not come into the equation in tower cranes! but thanks anyway.

Yo bob. Yup i sure tried the cit library plenty of times, but didnt find much that was very helpful.
