A wide range of waterproofing systems considered suitable by manufacturers for concrete bridge decks have been laid under experimentally controlled conditions on a concrete slab at the Transport and Road Research Laboratory. Their performance was monitored over a three year period. Many of the systems, including some of those with a British Board of Agreement Roads and Bridges approval certificate for use, were found to be unsuitable or ineffective. Severe damage was often caused during the laying of the base course due to penetration of aggregate into the membrane. The use of sand carpet asphalt to protect membranes from the effects of base course aggregate overcame this problem, but the interface bond between membrane and sand carpet was weaker than that for base course road surfacing materials. Where membranes were punctured or leaked, water transmission was much greater where there was poor bond between the concrete and the membrane. Resinous primers gave a better bond to the concrete than their bituminous counterparts. The results showed that the test programme current during the period of the trial for approval certification of waterproofing membranes is inadequate as it does not cover the full range of conditions to which membranes are subjected. Tests are required to cover the effect of hot aggregate, bond, moisture content of the deck and waterproofing integrity over the ambient and asphalt temperature range. This will necessitate the development of improved waterproofing systems.

Hello.
I was wondering if someone has this paper:
Determinition of p-y curves using inclinometer data - Brown DA, Hidden SA, Zhang S
Geotechnical Testing Journal 1994;17(2):150-158
Thanks

Title : Prevention of Progressive Collapse in Multistory Concrete Buildings
Author : F. Humay, S. Baldridge and S. K. Ghosh
Publisher : Structures and Codes Institute and International Code Council
Year : 2006
Language : English
Title: SP-127: Earthquake-Resistant Concrete Structures--Inelastic Response and Design
Publisher: American Concrete Institute
Publication: Special Publication
Date: October 1, 1991
Volume: 127
Pages: 554
Language: English
Abstract SP127:
This new special publication covers areas of: - Description of earthquake ground motion - Performance of systems and components in past earthquakes - Experimentally observed inelastic behavior of systems and components - Modeling hysteretic response of concrete members - Inelastic analysis - Deformability of structural components - Seismic design - Seismic detailing This publication helps provide economical new buildings with an enhanced seismic safety.
The seismic isolation technology helps in protecting structures from earthquake damage. This new book provides both theory and practical aspects of seismic isolation technique. It contains the necessary mathematical tools and introduces the empirical methods with detailed design and documentation material of type that a structural engineer would need to implement isolation technique. Authors: Trevor E. Kelly, R. Ivan Skinner and Bill (W.H.) Robinson. 373 pages.
I have attached an image of its cover for your reference.

Hello,
I need the following paper,
"Simplified nonlinear analysis of flexible retaining walls in soft soil",
Guo Yurong & Zou Yinsheng
any other paper or reference in modeling the construction sequence of an excavation or tieback wall using a beam-on-elastic foundation/winkler model would be welcome.
1.1 SCOPE
This Standard provides a guide to products and procedures for the painting of buildings for general domestic, commercial and industrial use.
The Standard does not include a specific recommendation for the long-term protection of iron or steel exposed directly to the atmosphere or to internal climates likely to have aggressive environments which are dealt with in AS/NZS 2312.
1.2 OBJECTIVE
The Standard is intended to assist those with interest in building design and maintenance such as trades people, architects, builders or building owners in the preparation of painting specifications for inclusion in contracts. It should not be called up in contracts without also specifying the detail to be derived from it.
In providing guidance on the preparation of painting and repainting specifications for surfaces forming parts of buildings, the Standard necessarily gives choices of paint types for use in different areas. For each contract, the architect, or owners, should draw up a complementary painting schedule to detail the options that are to be used together with a colour schedule. This Standard can then be referred to when specifying the necessary preparation, the coating system and the methods and conditions of application.
NOTE: Information on the preparation of painting specifications is given in Section 9 and Appendices A and B. Information on inspection and testing is given in Appendix C.
