Autocad 2009 (x32) Ripped

[Image: info.png]
The link is from ali43. This post was stored in Bad Posts and now after checking is posted here.
This is a ripped installation (513MB) including the X-Force key generator and need only serial (no product code).
Must be installed (is not portable as ali43 told us) but is a short installation. Must be installed in a computer where dotnetfx and directx was installed before (the ripped installation doesn't contains those components).
Installed in Windows 7 32 bit.

BS EN 1708-1:2010 Welding — Basic welded joint details in steel Part 1: Pressurized components

Author: CEN/TC 121 | Size: 1.64 MB | Format: PDF | Publisher: CEN | Year: 2010 | pages: 76

[Image: 13968067412710568326.jpg]


[Image: info.png]

The purpose of this European Standard is to exemplify commonly accepted welded connections in pressure systems. It does not promote the standardization of connections that may be regarded as mandatory or restrict development in any way. Stress analysis rules should be considered if necessary.
This standard contains examples of connections welded by:
 Manual metal-arc welding with covered electrode (111);
 Submerged arc welding (12);
 Gas shielded metal arc welding (13);
 Tungsten inert gas arc welding; TIG-welding (14);
 Plasma arc welding (15) processes (process numbers according to EN ISO 4063) in steel pressure systems. Other processes by agreement.
This standard covers welded joint details in steel, but can be applied to other metallic materials. In such cases the shape and dimensions of the weld should be checked. The estimation of the suitability of welded connections for special service conditions, for example corrosion and fatigue are not specially considered.

  Remediation of Brownfield Land
Posted by: ir_71 - 02-23-2011, 05:56 AM - Forum: Journals, Papers and Presentations - Replies (1)

Remediation of Brownfield Land

Author: Steve Angel, Keith Bradshaw, Dr Chris A Clear, Dr David Johnson, Dr Martyn Kenny, Dr Bill W Price, Michael Southall | Size: 1.87 MB | Format: PDF | Publisher: BCA | Year: 2004 | pages: 63 | ISBN: 0721016030

[Image: 16300085186152573315.jpg]


[Image: info.png]

This document provides guidance on the use of Stabilisation/Solidification (S/S) for the remediation of land affected by contamination, as commonly found on brownfield land or derelict sites. Cement and lime are widely used for stabilising natural soils to improve their engineering properties, and specifications and extensive guidance are available. Although S/S can be considered a natural extension of soil stabilisation techniques, it is more difficult to design, plan and implement: this is because of the potentially complex nature of soils and contaminants within brownfield or derelict sites. Accepting that the use of S/S is not as widespread as soil stabilisation, it has regularly been successful in remediating many types of derelict or contaminated land. A necessary precursor to any remediation is a risk assessment to establish the extent and nature of any hazardous contamination and so develop a remediation strategy to manage the risk. It is at this stage that S/S is assessed as a remediation option. Where S/S is found practicable, a full remediation design is carried out through a combination of laboratory and site trials before full site implementation. This document is an overview of the whole process, from the initial risk assessment to completion of the remediation. It is for general guidance only and must not be considered a substitute for the necessary site-specific documentation. All remediation work undertaken on land affected by contamination must be carried out to a site-specific working plan, drawn up by skilled professionals in liaison with main contractors or specialist subcontractors. This site specific working plan includes a comprehensive set of remediation objectives that are agreed with the Regulator appropriate to the site. S/S is a useful technique for treating particular wastes before disposal to landfill and parts of this document may be helpful for those involved with waste treatment. However, the general use of S/S for waste treatment is such a large and complex topic that it is outside the scope of this guidance.

  DISCOVERY BRIDGE OVER MISSOURI RIVER
Posted by: mowafi3m - 02-22-2011, 10:05 PM - Forum: Bridge (Project and Technology) - No Replies

DISCOVERY BRIDGE OVER MISSOURI RIVER

[Image: 24962896259912118399.jpg]

[Image: info.png]
SUMMARY
For the Discovery Bridge project, we provided plans for both concrete girder and steel girder designs. A major emphasis was placed on constructability throughout the design effort. The girder sections’ length and depth were adjusted to stay within the capabilities of nearby shops and the HPS70W flange plates were limited to 2 inch thickness because there are three producers that can provide plates up to 2 inch thickness but only one that can supply plates over 2 inches thick. These limits helped determine the best span arrangement, girder size, and girder spacing to use. The concrete girder design team was required to use the same span arrangement as the steel design, but was not limited to the same girder depth. We received three bids on the project – all for the steel option with the low bid being more than $300,000 below the estimate. No bids were received for the concrete girder option. The construction time estimated for this project was three years, but the contractor was able to complete the bridge more than a year ahead of schedule.

  MONITORING STEEL GIRDER STABILITY GOR SAFER BRIDGE ERECTION
Posted by: mowafi3m - 02-22-2011, 09:56 PM - Forum: Bridge (Project and Technology) - No Replies

MONITORING STEEL GIRDER STABILITY GOR SAFER BRIDGE ERECTION

[Image: 36623990196575323497.jpg]

[Image: info.png]
SUMMARY
The stability of steel plate girders during erection should be given special attention because the lateral support on the compression flange might temporarily not be present. Rules of thumb have been adopted by contractors to check the stability of cantilever or simply supported girders under erection using the maximum L (unbraced length) over b (compression flange width) ratio, beyond which lateral torsional buckling failure would occur under the girder’s self-weight. In order to check the rules of thumb, closed-form equations for the maximum L/b ratios of cantilevers and simply supported girders were developed following the current AASHTO LRFD code, and parametric studies were conducted for various girder sections. Finite element analyses (FEA) were conducted on a girder section for both the cantilever and the simply supported case to further understand the lateral-torsional buckling behavior of the girder under self-weight and identify the maximum L/b ratio through a trail-and-error approach, as well as verify that bracing the top tension flange at the cantilever free end would be more effective to prevent lateral torsional buckling than bracing the bottom compression flange.

  GUSSET PLATE SCREENING AND ANALYSIS ON THE HAWK FALLS BRIDGE
Posted by: mowafi3m - 02-22-2011, 09:49 PM - Forum: Bridge (Project and Technology) - No Replies

GUSSET PLATE SCREENING AND ANALYSIS ON THE HAWK FALLS BRIDGE

[Image: 31848928547472780433.jpg]

[Image: info.png]
SUMMARY
In the aftermath of the I-35W Bridge collapse in Minnesota, the Federal Highway Administration issued a technical advisory to bridge owners to check the status of gusset plates on similar bridges. In response, the Pennsylvania Turnpike Commission initiated a screening program for the analysis of the Pennsylvania Turnpike’s Hawk Falls Bridge. The 51-year old, 740 ft long bridge spans Mud Run and contains a three-span continuous, haunched Warren deck truss. An analysis of the bridge was performed using BAR7. The gusset plates were grouped into representative types and each type was analyzed considering worst-case loads. A finite element model was developed, which verified the results of the hand calculations, finding some stresses above allowable values, but below material yield strength. A monitoring program was subsequently implemented, and data will be collected through sensors and strain gages for one year to accurately evaluate the bridge and make decisions regarding future rehabilitation.
