BS 5950 Structural use of steelwork in building, Part 1: Code of practice for design - Rolled and welded sections has undergone major amendment. Almost every Clause of this widely used Standard has changed in some way; some of the changes are technical in nature, others are editorial and do not alter the recommendations for building design. The revised Standard, referred to as BS 5950-1:2000, became effective on 15 August 2001.
The aim of this publication is to ease the transition to BS 5950-1:2000 by guiding designers through the major technical amendments to the Standard. A short description of each important change is provided, and simple worked examples illustrate the revised design procedures.
The major amendments to BS 5950-1 include revised rules for checking the stability of frames, changes to the method for selecting an appropriate steel sub-grade and the introduction of the effective-area method for class 4 slender sections. On the subject of member design, the greatest change relates to lateral-torsional buckling, where the n-factor method has been removed. Changes have also been made to the Clauses on shear buckling, stiffener design, tension members, compression members, combined axial load and bending, and the design of column bases. Elsewhere, important changes have been made to the rules relating to the in-plane stability of portal frames, prying forces and the transverse strength of fillet welds.

BORING, SAMPLING AND FIELD TESTING IN SOIL INVESTIGATION: OPTIMAL DECISIVE ASPECT FOR GEOTECHNICAL EXPLORATION
Author: A. B. M. Saiful Islam (Author), Mohammed Jameel (Author), Mohd Zamin Jumaat (Author) | Size: unknown MB | Format:PDF | Publisher: VDM Verlag Dr. Müller (February 24, 2011) | Year: 2011 | pages: 100 | ISBN: 978-3639336993
This book presents an overview of the rules for boring spacing, boring depths requirements along with sampling type and depths as well as its design applications, in the light of the experience accumulated in geotechnical investigation. The topics have been discussed in details. Also the number and type of field tests in soil form survey have been thrashed out her to see the variability of test procedure, apparatus used and their contribution in determining soil properties. The study reveals that there is no hard and fast rule for boring spacing or the depth to which boring are to be advanced. For collecting undisturbed soil sample Shelby tube sampler is suitable and it is a common practice in Bangladesh that Shelby Tube is gently hammered into the soil not employing the jacking system. For field test standard penetration test is very user friendly in context of Bangladesh and is most widely used for its simplicity of apparatus and ease of testing.

Dear all member,
I need this standard for more information to design a industrial concrete slab on ground (conform to ACI 360-10). If anyone have this, please share for me.
Thank you in advance.
This Specification and companion Commentary (hereinafter referred to as the Specification) applies to industrial pallet racks, movable shelf racks, rack supported systems and stacker racks made of cold-formed or hot-rolled steel structural members. Such rack types also include push back rack, pallet flow rack, case flow rack pick modules and rack supported platforms. This Specification is intended to be applied to the design of the storage rack portion of any rack structure that acts as support for the exterior walls and roof, except as noted. It does not apply to other types of racks, such as drive-in or drive-through racks, cantilever racks, portable racks, or to racks made of material other than steel.

ABSTRACT A study was undertaken to investigate the composite behavior of a Geosynthetic Reinforced Soil (GRS) mass. Many studies have been conducted on the behavior of GRS structures; however, the interactive behavior between the soil and geosynthetic reinforcement in a GRS mass has not been fully elucidated. Current design methods consider the reinforcement in a GRS structure as “tiebacks” and adopt a design concept the reinforcement strength, Tf, and reinforcement spacing, Sv, have the same effects on the performance of a GRS structure. This has encouraged the designers to use stronger reinforcement at larger spacing, as the use of larger spacing will generally reduce time and effort in construction. A series of large-size Generic Soil-Geosynthetic Composite (GSGC) tests were designed and conducted in the course of this study to examine the behavior of GRS mass under well-controlled conditions. The tests clearly demonstrated that reinforcement spacing has a much stronger effect on the performance of GRS mass than reinforcement strength. An analytical model was established to describe the relative contribution of reinforcement strength and reinforcement spacing. Based on the analytical model, equations for calculating the apparent cohesion of a GRS composite, the ultimate load carrying capacity of a reinforced.....

Dear Admin and all staff, welcome back with CivilEA. I was wondering what happened with the pints, I mean that at each thread or post or something else we were getting some points which were displayed bellow the thanks. There is available that option anymore or you lost that information or you have just modified this fact?
