南山佛法身舍利塔动力弹塑性分析
Dynamic elastoplastic analysis of the Nanshan Buddhist Body Relic Pagoda
摘要
Abstract
The Nanshan Buddhist Body Relic Pagoda is a newly constructed heritage-style land-mark within Nanguo Temple,a national 4A-level tourist attraction.This reinforced concrete and steel reinforced concrete composite frame-core wall system,designed for a service life of 100 years,initially lacked full consideration of site conditions and design lifespan in its rare-earth-quake design.Using MIDAS Gen,this study established a finite element model and conducted ad-justed dynamic elastic/elastoplastic time-history analyses on the structure under three seismic waves(two natural and one artificial).Fiber models were employed for elastoplastic analysis to evaluate its shear forces,overturning moments,deformations,yielding states,hysteretic energy dissipation,and overall energy response.The results demonstrate the following:(1)story stiff-ness variations correspond to the structural layout and member configuration;(2)elastoplastic story drift ratios all satisfy the code limit of 1/100,with peak values corresponding to the struc-tural arrangement;(3)the core-tube shear walls exhibit moderate yielding and substantial energy dissipation,whereas the outer frames show minimal yielding;and(4)superior seismic energy dissipation capacity of the structure ensures strong earthquake resistance.Analysis confirms that,despite initial design limitations,the Nanshan Pagoda's improved seismic design and detailing pro-vide reliable safety and excellent seismic performance,providing valuable guidance for similar structures.关键词
