19、 P. TungJairo UribeThis guide presents simplified methods and design techniques that facilitate and speed the engineering of low-rise buildings within certain limitations. Material is presented in an order that follows typical design process with procedures introduced as the designer will need them

20、in the course of a building design. Much of the information presented in this guide is derived from ACI 318, ASCE 7, and the 2015 International Building Code (IBC) (International Code Council 2015). The quality and testing of materials used in construction are covered by references to the appropriat

21、e ASTM standard specifications.Whereas many of the tables, charts, and values included in this guide originated from the aforementioned reference documents, they have been modified or reorganized to be more conservative, to match design process flow, or better support the holistic and simpli-fied de

22、sign approach presented.Although this guide is not written in mandatory language, the information is presented in such a manner that a structure designed following this guide will, in principle, comply with the codes and standards on which it was based. Although this guide is written in nonmandatory

23、 language, it is meant to be applied as a whole, because the simplified provisions are interdependent, and it would be unsafe to employ only a portion of this guide and disregard the remainder. This guide is not a code and is not deemed to satisfy ACI 318, ASCE 7, and the International Building Code

24、 (International Code Council 2015). This guide is expected to be especially useful in the education and training of engineers in reinforced concrete design of low-rise structures of small to medium floor areas.There are many options within these standards that are not considered in this guide, such

25、as the use of supplementary cementi-tious materials in concrete mixtures. As this guide will be used as a design aid, it is the licensed design professionals responsibility to ensure that the structure design satisfies the requirements of ACI 318, ASCE 7, the International Building Code (Internation

26、al Code Council 2015), and the legal requirements of the local jurisdiction. The original draft of the guide, published as ACI IPS-1 (2002), was produced by a Joint Committee of Instituto Colombiano de Normas Tcnicas y Certificacin (Colombian Institute for Technical Stan-dards and Certification) (IC

27、ONTEC) and Asociacin Colombiana de Ingeniera Ssmica (Colombian Association for Earthquake Engineering) (AIS).The initial drafting of ACI IPS-1 (2002) was motivated by frequent worldwide discussions that reinforced concrete codes might be unnecessarily sophisticated for some applications, such as sma

This guide used ACI IPS-1 (2002) as a basis, with information derived from ACI 318, ASCE 7, and the International Building Code (International Code Council 2015).This guide presents simplified approaches to assist engineers in designing l

32、simplified strength models(f) Other limit states accounted for by minimum dimensions(g) Conservative loads and simplified analysis guidelines(h) Simplified geotechnical information to help define soil-bearing capacity(i) Shear walls as the seismic-force-resisting system(j) Material and construction
