新式建筑隔震沟构造做法的设计研究

Design and Research on Construction Method of New Building Seismic Isolation Trench

随着《建筑隔震设计标准》GB/T 51408—2021的实施,在云南这类高烈度区重点设防类建筑(如:学校、医院等),采用隔震设计更符合结构设计合理性的要求。常用的四类隔震沟做法中,前三类构造除应用工况有局限以外,做法本身没有技术缺陷。而第四类构造,其本身具有一定的技术缺陷,而使用又较为广泛。因此,尝试修补其技术缺陷颇有意义。该文通过对相关隔震构造图集提供的几类常用隔震沟构造做法,在实际应用中存在问题的研究,提出了一种新式的隔震沟构造做法。该做法继承了常用做法的功能特点,同时具有普适性好、不影响建筑整体美观等特点。

With the implementation of the Standard for Seismic Isolation Design of Building(GB/T 51408—2021),the seismic isolation design with a more reasonable structure design is adopted for key fortification buildings(such as schools,hospitals,etc.)in high-intensity areas such as Yunnan Province.Among the commonly used four types of seismic isolation trenches,the first three types of structures have no technical defects except for their limitations in application conditions.However,the fourth type of structure itself has certain technical defects while it is widely used.Therefore,it makes sense to try and repair its technical defects.This paper puts forward a new construction method of seismic isolation trench by studying the problems existing in the practical application of several common construction methods of seismic isolation trench provided by relevant structural atlases.This method inherits the functional characteristics of common methods while having good universality and not affecting the overall aesthetics of the building.
