16G101-2 Drawing Rules and Standard Detailing Drawings of Ichnographic Representing Method for Construction Drawings of R.C. Structures (Cast-in-situ concrete slab-stairs) is the revised version of 11G101-2 Drawing Rules and Standard Detailing Drawings of Ichnographic Representing Method for Construction Drawings of R.C. Structures (Cast-in-situ concrete slab-stairs). According to the updated 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 in recent years, contents in the drawing collection have been systematically revised, and details of CTa and CTb stairs with slide bearings, of which the stair slab consists of flight and upper landing slab, are included in this version. This drawing collection is applicable to cast-in-situ concrete slab-stairs in seismic design with seismic precautionary intensity 6~9. There are 12 types of cast-in-situ concrete slab-stairs in this drawing collection. Among these types, AT~GT stairs are applicable to stairs that are not considered in seismic analysis of main structures, and ATc stairs are applicable to stairs in frames that are considered in seismic analysis of main structures, while ATa, ATb, CTa and CTb stairs are applicable to stairs where sliding bearings are adopted to reduce the impact of stairs on main structures (frames).英文名称：ard Detailing Drawings of Ichnographic Representing Method for Construction Drawings of R.
