摘要
为研究大体积混凝土底板跳仓法施工技术及温度应力,文中以福建某商务办公楼为例,通过ANSYS有限元软件建立模型,对跳仓法施工下大体积混凝土的温度场和温度应力进行模拟分析,揭示温度应力的形成机制及其影响因素,并提出优化施工方案,以减小温度应力,确保结构的安全与耐久性.
Abstract
In order to study the construction technology and temperature stress of jump-off method of large volume concrete floor.This paper takes a commercial office building in Fujian as an example,establishes a model by ANSYS finite element software,simulates and analyzes the temperature field and temperature stress of mass concrete under the construction of bin hopping method,reveals the formation mechanism of temperature stress and its influencing factors,and proposes an optimal construction scheme to reduce temperature stress and ensure the safety and durability of the structure.
