15、ildings is the result of an agreement between the American Concrete Institute and two Colombian Institutions: the Instituto Colombiano de Normas Tcnicas y Certificacin (Colombian Institute for Technical Standards and Certification) and the Asociacin Colombiana de Ingeniera Ssmica (Colombian Associat
16、ion for Earthquake Engineering). The document was motivated by frequent worldwide criticism that current reinforced concrete codes might be unnecessarily sophisticated for some uses, such as small low-rise structures. The need for guidelines and minimum requirements for the design and construction o
17、f structures that fall in these categories is felt throughout the world. The document is expected to be especially useful in the education and training of young engineers in reinforced concrete design. A useful precedent for the drafting committee was the simplified rules for design and construction
18、 of masonry one- and two-story dwellings contained in some building codes. Current knowledge on reinforced concrete behavior obtained through experimentation and experience, and its status and dissemination as a structural material used worldwide, made the task of development of a simplified design
19、and construction document, not only feasible, but challenging. Among the subjects covered are: aggregate size; allowable soil bearing capacity; analysis and design; beams; bearing strength; columns; combined footings; concrete cover; concrete curing; concrete mixing and transportation; concrete mixt
20、ure proportions; concrete quality, mixing, and placing; concrete strength evaluation; construction joints; definitions of terms used; design and construction procedures; design for axial load with flexure; design for flexure; design for shear; development length and splicing of reinforcement; drawin
21、gs and specifications; durability requirements; embedded pipes; flexural and axial loads; floor systems; footings; form removal; formwork; foundation mats; foundations; geotechnical investigation; girders; grade beams; inspection; joists; lateral load resistance; layout of the structural system; lim
22、it states; loads (dead, live, rain, snow, wind, earthquake, and soil lateral pressure); materials for reinforced concrete construction; minimum depth for members; one-way and two-way slabs; project specifications; reinforcement details; retaining walls; shear and torsion; shear walls; slab systems;
23、slab-column systems; slabs-on-grade; special provisions for seismic design; spread footings; stairways and ramps; standard hooks; strength and serviceability; structural drawings; wall footings; walls; water tanks. The following features were the general guidelines for the Essential Requirements for
24、 Reinforced Concrete Buildings: The aim of the document is to provide rules for the design and construction of common, low-rise structures of small to medium floor areas. The design rules are based on simplified accepted strength models; other limit states are accounted by specified dimensional requ
25、irements. The minimum dimensional requirements contained in the document are intended to replace the need for more-sophisticated analysis and design procedures. Material and construction requirements are aimed at available steel grades and concrete of medium strength that could be site mixed. The do
26、cument is self-contained; therefore, loads and simplified analysis procedures are included as well as geotechnical exploration requirements to be used in defining a soil bearing capacity and minimum acceptable construction practice guidelines. Earthquake-resistant requirements are based on the use o
27、f structural concrete walls (shear walls) that limit the lateral deformations of the structure and provide lateral strength. The document is written in mandatory language. Where explanatory non-mandatory material was required, this material was included at the appropriate places and a special cursiv
28、e type font was employed to indicate the non-mandatory character. -iii- Essential Requirements for R/C Buildings In a departure from traditional code-related publications, the document contains graphs and graphical explanations. Requirements are introduced in the order needed in the course of a desi
29、gn. The design can be carried out using solely the document and a hand calculator without need for a computer. For international use, SI Metric and US Customary Units versions in English and a SI Metric version in Spanish of the document were produced. Acknowledgments Icontec-AIS Joint Drafting Comm
