砼框架结构抗震设计中浅基础设计探讨

砼框架结构抗震设计中浅基础的设计是众值烈度(多遇烈度)下的弹性基础设计,多遇地震作用均应参与组合,柱根设计内力为众值烈度(多烈度)下处于弹性状态时,最不利组合内力经内力调整设计的延性框架柱根内力,浅基础的设计按弹性基础设计时不需要考虑基础的延性要求,设计计算应遵循地基基础抗震设计原则,满足地基基础抗震设计要求。

Exploration on Hallow Foundations Design in Concrete Structure Seismic Design

The design of shallow foundations in the seismic design of the concrete frame structure is the elastic foundation design under multi-intensity,the effect of multi-earthquake should be involved in the combination,the design internal forces of column root is internal forces of ductile frame columns root that the most unfavorable combined internal forces are adjusted when multi-case intensity is in the elastic state.The design of shallow foundation does not need to consider ductility requirements of foundation in the elastic foundation design,the calculation should follow seismic design of foundation principles,meeting the seismic design requirements of foundation.
