Dear friends,
there is new edition ot EN 934-2, which supersedes EN 934-2:2009, namely - EN 934-2:2009+A1:2012 "Admixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling".
I'll be thankful if someone who has it or could find it - share it with me.

Author: E. J. Cording, J. L. Long, M. Son, D. Laefer, B. Ghahreman | Size: 633 KB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2010 | pages: 20
Ground movements during excavation have the potential for major impact on
nearby buildings, utilities and streets. Increasingly ground movements are controlled
at the source. They are assessed by linking the ground loss at the excavation wall to
the volume change and displacements in the soil mass, and then to the lateral strains
and angular distortion in structural bays or units, and are related to damage using a
damage criterion based on the state of strain at a point. Numerical and physical models
of excavation-induced building damage were used to vary parameters and develop
procedures for assessing distortion and damage. Examples of building distortion
and damage are presented for brick bearing wall structures of the 1800’s and early
1900’s, as well as later frame structures, that illustrate how geometry, era of construction,
stiffness, and condition influence building response to ground movement.

Fatigue Design of Steel and Composite Structures: Eurocode 3: Design of Steel Structures, Part 1-9 Fatigue; Eurocode 4: Design of Composite Steel and Concrete Structure
Author: Alain Nussbaumer, Luis Borges, Laurence Davaine | Size: 9.2 MB | Format:PDF | Quality:Unspecified | Publisher: Ernst & Sohn | Year: 2011 | pages: 334 | ISBN: 9783433029817
This volume addresses the specific subject of fatigue, a subject not familiar to many engineers, but still relevant for proper and good design of numerous steel structures. It explains all issues related to the subject: Basis of fatigue design, reliability and various verification formats, determination of stresses and stress ranges, fatigue strength, application range and limitations. It contains detailed examples of applications of the concepts, computation methods and verifications.

This paper examines the state of practice of the design and construction of excavations in soft soils. The review is based primarily on the author's experience, published case histories, and discussions with colleagues involved in the design and construction of excavations in soft soils. It is not a survey of current practices, because such a survey would not be practicable, or even useful, because of many variations in local practices. The paper examines major milestones in the development of the design and construction of excavations in soft soils, and reviews recent developments and trends in design and construction practices.
Traditionally, the design and construction of excavations is handled contractually as a design-build contract, with the responsibility for the design and construction of the shoring system delegated to the contractor. However, new developments in analytical design tools and construction methods, as well as wider recognition of the potential legal consequences of the impacts of excavation-induced deformations on existing structures, and the need to address these issues in advance of construction, is leading to new approaches in the design and construction of excavations in general, and for soft soils in particular. Recent innovations in construction methods, such as the introduction of deep-soil mixing and jet grouting, are providing greater flexibility in the design and construction of excavations for deformation control. This paper reviews these developments and summarizes data from case histories to illustrate practical application of these new methodologies and construction techniques for the design and construction of excavations in soft soils.

Many structures located close to excavations are damaged by excessive ground movements during construction. This is partly due to limitations of commonly used methods to design the excavation support system. The authors propose using a displacement-based design method that focuses on designing to keep movements within allowable values. A step-by-step approach for the method is described and illustrated for a deep excavation into soft clay.

Measured performance of a 26 m deep top-down excavation in downtown Shanghai
Author: Yong Tan and Mingwen Li | Size: 3.9 MB | Format:PDF | Quality:Unspecified | Publisher: anadian Geotechnical Journal | Year: 2011 | pages: 16
Via a long-term comprehensive instrumentation program, the performance of a 26 m deep metro station excavation
constructed by the top-down method in downtown Shanghai was extensively examined. The measured excavation responses
included diaphragm wall deflections, wall settlements, ground settlements, uplifts of interior steel columns, axial
forces of propping struts, groundwater table levels, and settlements of adjacent buildings and utility pipelines. Based on the
analyses of field data, the following major findings were obtained: (i) the concrete struts along with the floor slabs effectively
suppressed later wall movements and consequently reduced the chance that the maximum wall deflections would occur
above the excavation surfaces, (ii) with the progress of excavation to a lower depth, the diaphragm walls underwent a
serrated settlement pattern over time, (iii) no significant post-excavation wall deflection occurred, (iv) the relationship between
the interior column uplifts and the maximum wall deflections can be described by a linear equation, and (v) most system
loads due to soil removal were carried by the concrete struts along with the floor slabs. The struts sustained mainly the
released earth pressures due to the exposure of the adjacent portions of diaphragm walls, and the soil removal distant from
the struts imposed limited effects on the strut axial forces.
