烟台市文化中心图书馆与博物馆之间连接体抗震设计

Anti-seismic design of the joint component between library and museum of the Yantai cultural center

烟台市文化中心是烟台市为提升城市形象而打造的重点项目,该项目由图书馆、博物馆、文学馆和两层地下车库组成,地上三塔通过连廊连成一体,主楼采用框架-混凝土剪力墙结构,连廊采用钢结构,连廊支座采用抗震弹性支座,图书馆与博物馆之间连廊中部支撑于钢管混凝土柱与混凝土墙组成的核心筒上。本文重点分析图书馆与博物馆之间连接体的受力特点,通过分析其动力特性进而对连廊端部弹性支座的受力、变形及选型进行论证。通过对计算模型进行简化,采用抗震性能化的设计方法,重点分析在小震和大震作用下连接体的动力响应和整体参数,并根据连接体的最大位移选取合适的抗震弹性支座。在保证连接体结构受力性能的前提下,确保支座的位移及核心筒的变形在规范要求的范围内,同时保证连接体处人体的舒适度要求。

The Yantai Cultural Center project is a key project of Yantai City to enhance the image of the city,which consists of a library,a museum,a literary hall and a two-story underground garage.The three towers on the ground are connected by outdoor corridors.The main body adopts a concrete frame-shear wall structure,and the corridor adopts a steel structure.The corridor adopts anti-seismic elastic support,and the middle part of the corridor between the library and the museum is supported on the Core Tube composed of concrete-filled steel tube columns and concrete walls.This article focuses on analyzing the force characteristics of the connecting body between the library and the museum,and demonstrates the force,deformation and selection of the elastic support at the end of the corridor through analyzing its dynamic characteristics.By simplifying the calculation model and adopting the design method of anti-seismic performance,the analysis focus on of the dynamic response and overall parameters of the connecting body under the action of small and large earthquakes and the appropriate seismic elastic support is selected according to the maximum displacement of the joint component.Under the premise of ensuring the structural stress performance,it is ensured that the displacement of the support and the deformation of the core tube are within the scope of the code,and ensure the comfort of the human body at the tower.
