- Tall building foundations: design methods and applications
- BS 8004:2015+A1:2020
This paper will review some of the challenges faced by designers of foundations for very tall buildings, primarily from a geotechnical viewpoint. Some characteristic features of such buildings will be reviewed and then the options for foundation systems will be discussed. A three-stage process of foundation design and verification will be described, and the importance of proper ground characterization and assessment of geotechnical parameters will be emphasised.
This is an important design standard for geotechnical and structural engineers, setting out the fundamental rules that should be followed in the design of both shallow and deep foundations. It gives recommendations for the design, construction, testing, monitoring and maintenance of foundations in accordance with BS EN The foundation types covered include spread foundations, pile foundations including helical pile foundations and underpinning.

ABSTRACT Regarding the increasing expansion of construction in Tehran, the design and construction of raft or grid concrete foundations are very common for tall buildings. Winckler springs are often used by professionals to model soils in the design of flexible concrete foundation. However, it presents a substantial problem because the Winckler springs are not coupled. Such a subgrade reaction theory is too simplified, i. Continuum mechanics theory and numerical simulation tools are available to be used for soil modeling but they are time consuming and most engineers prefer to use Winckler springs to model the soil. In the presented research, a computer program was firstly developed based on finite elements method. It could model a flexible foundation on springs but the springs are coupled by considering stress distribution within soil mass.

The purpose of the document is to present an administrative procedure to institutionalize a clear method for ensuring that safe Working Platforms are in place for foundation construction equipment. This document also serves as a suggested framework by which allocation of responsibility can be communicated and determined long before work is performed on the jobsite. This short, easy-to-follow guide is intended for the preliminary design and selection of helical piles and anchors.
Foundation work is not the glamorous side of home building. It is hard, dirty work. But its also the work upon which all other work rests, and so a good foundation is critical to every home. No source of knowledge on foundations and concrete work isMoreFoundation work is not the glamorous side of home building. No source of knowledge on foundations and concrete work is better respected or more widely followed than that provided by the authors of Fine Homebuilding magazine. This latest edition from the editors of Fine Homebuilding is the biggest and most authoritative volume yet on the subject.
Post-grouting, in the context of this workshop and report, refers to the alternative design and construction of base-grouted drilled shafts wherein a grout distribution system is installed during construction and used to grout the base under pressure after the drilled shaft concrete has gained adequate strength, resulting in a stiffer axial-compression load-displacement relationship and additional possible ground improvement effects. This report is structured to follow the workshop program: workshop presentations outlined the state of practice and views from owners, engineers and contractors on acceptance of post grouting methods for drilled shafts; and subsequent workshop discussions attended by a small invited group of participants focused on identifying areas of agreement and disagreement on post-grouting best practices, acceptance criteria, design and verification procedures, and inspection requirements. A partial list of attendees of the open and closed sessions is provided as Appendix A, and copies of presentations are included as Appendix B. FHWA and Caltrans are the primary audiences for this report, and its content will be used to develop a roadmap for deploying the findings into policy and practice. The secondary audience is the broader industry group, and the report content will be disseminated in a variety of formats.

Здесь. Халохот приблизился к внешней стене и стал целиться. Ноги Беккера скрылись из виду за поворотом, и Халохот выстрелил, но тут же понял, что выстрел пришелся в пустоту. Пуля срикошетила от стены.
