ASCE 20-96 is a standard guideline for the design and installation of pile foundations, published by the American Society of Civil Engineers (ASCE). It provides a rational basis for the engineering approach to pile foundation design, taking into account published model building codes and general standards of practice. It covers topics such as administrative requirements, pile shaft strength requirements, soil-pile interface strength requirements and capacity, design loads, design stresses, construction and layout guidelines for pile design, and installation guidelines for pile construction. It also includes information on applicable standards from ASTM, AWPA, and ACI, as well as an appendix on partial factors of safety.

You should always check the original source and cite it properly if you use any information from these files.
Another option is to use a library that has a subscription to ASCE Library or a physical copy of ASCE 20-96. You can search for libraries near you that have this standard using WorldCat, a global catalog of library collections. You may be able to borrow the book or access the online version through the library's website or computers. However, you may need a library card or membership to do so.
In conclusion, ASCE 20-96 is a valuable resource for engineers who work with pile foundations. However, it is not easy to find a free download of this standard online. You may have to use alternative methods such as document-sharing platforms or libraries to get a copy of this standard. However, you should always respect the copyright and citation rules of ASCE and other sources when using this standard.Here are some more paragraphs for the article:
Why is ASCE 20-96 important for pile foundation design? Pile foundations are deep foundations that transfer loads from structures to the underlying soil or rock layers. They are used when the surface soil is not suitable or sufficient to support the structure, or when the structure requires a large load capacity or resistance to lateral forces. Pile foundations consist of piles, which are long and slender elements that are driven, drilled, or jacked into the ground, and pile caps, which are concrete slabs that connect the piles and distribute the loads to them.
Pile foundation design is a complex and challenging task that requires a thorough understanding of the soil conditions, pile behavior, load combinations, and failure modes. ASCE 20-96 provides a comprehensive and consistent guideline for engineers to follow when designing and installing pile foundations. It helps to ensure the safety, reliability, and efficiency of pile foundations for various types of structures and applications.
What are the main features of ASCE 20-96? ASCE 20-96 is divided into nine chapters and one appendix. The first chapter introduces the general scope and purpose of the standard. The second chapter outlines the administrative requirements for pile foundation design, such as codes, specifications, permits, drawings, calculations, tests, and inspections. The third chapter specifies the pile shaft strength requirements, such as minimum cross-sectional area, allowable stresses, buckling resistance, and splice strength. The fourth chapter defines the soil-pile interface strength requirements and capacity, such as skin friction, end bearing, group effect, negative skin friction, and uplift resistance.
The fifth chapter describes the design loads for pile foundations, such as dead loads, live loads, wind loads, earthquake loads, water loads, ice loads, and impact loads. The sixth chapter determines the design stresses for pile foundations, such as axial compression stress, axial tension stress, bending stress, shear stress, and torsion stress. The seventh chapter provides construction and layout guidelines for pile design, such as pile spacing, alignment, batter angle, penetration depth, cutoff elevation, and lateral support. The eighth chapter gives installation guidelines for pile construction, such as equipment selection, installation methods, installation control, installation records, and installation problems. The ninth chapter lists the applicable standards from ASTM (American Society for Testing and Materials), AWPA (American Wood Protection Association), and ACI (American Concrete Institute) that are relevant to pile foundation design. The appendix presents partial factors of safety for different types of piles and soils. 0efd9a6b88
