Evaluation and Retrofitting of Building Foundations
Generally, in the case where any of such damages as differential sedimentation, inclination, cracks, and defects has been caused to foundations by an earthquake or consolidation settlement, a survey on the integrity of foundations is required. Great attentions should be paid to the sites, which may involve the risk of liquefaction or a settlement disaster, even if no differential settlement has been actually occurred. Nevertheless, for existing buildings, the actually-occurring phenomena such as differential settlement and inclination of the buildings and cracks in the foundation members tend to attract greater attention than the results of evaluations based on design calculation

This request goes out to the forum users who might happen to have a copy of the ISO 15686 standards 1-10 ( or any part thereof ) . I need it to complete my project on
structural reliability assessment and unfortunately my university does not have access to these
standards.
Please refer related link for details :

I had posted requests regarding other ISO codes earlier, which were positively replied to,
and am hoping that it happens again ( keeping my fingers crossed).
Dear members of Civilea
I need help.
I did CSM procedure manually of course with help of ETABS & excel
What 'target displacement' that I should enter at the pushover case for CSM procedure ?
Should I calculate first "the target displacement" as in FEMA 273/356 & enter that 'target displ. of FEMA 273/356' to the pushover case ?
Thanks
Paladin
GEOTECHNICAL ENGINEERING OF THE STABILITY OF NATURAL SLOPES, AND CUTS AND FILLS IN SOIL
The paper presents a critical review of the state of the art of geotechnical engineering of natural slopes, cuts and fills in soil. Topics which are covered include the pre and post failure mechanics at the micro and macro scale, including discussion of contractant and other strain weakening soils, creep, progressive and retrogressive failure and fissured clays. Geotechnical investigation requirements and methods for analysis of stability and deformations, and for analysis of post failure velocity and travel distance are reviewed. It is concluded that many slope instability hazards may be managed by traditional factor of safety methods, but that it is important that the post failure behaviour be considered. Observational, and risk assessment methods may be more appropriate than the traditional methods in many cases.

MECHANISMS AND RATES OF SLOPE MOVEMENTS IN FINE GRAINED SOILS
Mechanisms of slope movements are always the result of a complex stress-strain field induced by changes of boundary and environmental conditions (triggering factors). The slope response to triggering factors depends on soil properties and initial conditions and is categorised by different landslide styles. The major aim of this report is to stress the relationship existing between mechanisms and mechanics of slope movements induced by changes of boundary conditions.

The fourth in the highly respected Short Course Series, A Short Course in Soil-structure Engineering of Deep Foundations, Excavations and Tunnels, focuses on the three major geotechnical challenges of static soil-structure interaction problems. Deep foundations ? piles, barrettes, Multi-propped deep excavations and Bored and open face tunnels beneath cities.
This book gives both students and practising civil engineers an authoritative review of the state-of-the-art of designing deep foundations, excavations and tunnels. In addition, the case studies and numerical modelling

About the Book
Strength of Materials covers the study of the behaviour of structural and machine members under the action of external loads. Analysis is directed towards determining the limiting loads, that the member can stand before failure of the material or excessive deformation. To this end, three basic sets of relations can be obtained. The book highlights the mechanics of these conditions.
