Regulations of administration of seismic management of construction projects came into effect in China on September 1st,2021.Since then,the seismic performance requirements for new schools,kindergartens,hospitals,elderly care institutions,children's welfare institutions,emergency command centers,emergency shelters,radio and television buildings located in high seismic fortification intensity areas and key earthquake surveillance and protection areas have been upgraded,i.e.,from"ensuring seismic safety"to"maintain normal functionality".Therefore,the Research Institute of Standards and Norms Ministry of Housing and Urban-Rural Development released Technical guideline for maintaining normal functionality of buildings in earthquakes(RISN-TG046-2023)(the guideline for short)on May 12th,2023.In order to help users better understand the guideline,the background,process and contents of each chapter of the guideline were introduced,and the important provisions of the guideline were interpreted.Particularly,the flowchart of seismic design procedure for buildings to meet the requirement to maintain functionality was illustrated in detail.The guideline innovatively proposed the design concept of controlling both the displacement and acceleration responses to realizing the seismic protection of structural,non-structural components and equipment,which provides scientific and utility solution for achieving normal functionality of buildings in earthquakes.
