The reinforcing detailing of building structures in Taiwan’s local practice follows the evolution of  seismic design codes.  In early days, the reinforcing layout was based on results of Working Stress Design.  At that time, there was no ductility considerations included in the reinforcing details.  With the adoption of the ACI 318 Code from the United States, the Ultimate Strength Design method was utilized.  Afterwards, the possible failure modes of the non-linear structural behavior were to be considered in the structural detailing.  However, the standard reinforcing details of the American practice in conformance with the ACI Code were rare comparing with the Japanese engineering application.  Therefore, the reinforcing details and construction of RC structures in the early age of Taiwan’s practice were greatly influenced by the translated Japanese engineering documents. This phenomenon, the structural design follows the American ACI 318 Code and the construction follows Japanese type of practice, sometimes resulted in conflict and bothered engineers during construction. 
Because structural ductile details in Japanese practice were not as emphasized as American standards, and many books on the construction of rebar placing following the Japanese practice were also out-of-dated, these practice of reinforcing details did not meet RC design requirements of Taiwan codes.
Because Taiwan is located in the high seismic hazard area, the reinforcing details of the RC structures are extremely important.  However, the reference regarding reinforcing details that follows the local RC design codes are rare.  In order to improve the quality of the reinforcing steel construction, the Chinese Society of Structural Engineers and other associations published “The Construction and Quality Control of the Reinforcing Detail for Building Structures ”in 2013.  This document, based on the current Taiwanese design code, illustrates the aseismic details, material requirements, construction sequence of different types of elements, and the reinforcing details of RC structures.  This article describes the reinforcing details related to the ductility design, design considerations and their modification based on the code development.
