16G101-3 Drawing Rules and Standard Detailing Drawings of Ichnographic Representing Method for Construction Drawings of R.C. Structures (Spread footings, strip foundations, raft foundations and pile foundations) is the revised version of 11G101-3 Drawing Rules and Standard Detailing Drawings of Ichnographic Representing Method for Construction Drawings of R.C. Structures (Spread footings, strip foundations, raft foundations and pile foundations). According to the updated versions of codes GB 18306-2015 Seismic ground motion parameters zonation map of China, GB 50011-2010 Code for seismic design of buildings and its partial revision in 2016 and GB 50010-2010 Code for design of concrete structures (2015 version) et al., considering feedbacks from engineering practice and need of practical projects in recent years, contents in the drawing collection have been systematically revised, and details of cast-in-place concrete piles are included in this version. This drawing collection is applicable to the construction drawing design of all kinds of cast-in-situ concrete spread footings, strip foundations, raft foundations (ribbed and slab) and pile foundations. There are two parts in this drawing collection: drawing rules of IRM and standard detailing drawings of commonly used spread footings, strip foundations, raft foundations (ribbed and slab) and pile foundations made of cast-in-situ concrete.
