本科培养方案是高等学校实施人才培养的基本依据.加入《华盛顿协议》以后,为了适应高等教育教学改革发展的新形势、新要求,提高人才培养质量,探索工程教育认证背景下"以学生为中心、以输出为导向"的改革目标,完善本科培养方案势在必行.
基于二硫化钼这种摩擦滑移材料,设计并制作了1种新型摩擦滑移隔震支座,通过对该滑移支座进行相关的摩擦因数试验,获得了该装置摩擦因数计算公式.利用ABAQUS有限元分析软件,建立了应用该新型摩擦滑移隔振装置的5层试验框架及相应抗震结构的有限元分析模型,并探讨了该抗震与隔震结构模型在EL Centro波3种地震烈度水平单向输入下的位移和加速度响应的主要规律.研究结果表明:该新型摩擦滑移装置使得框架模型在隔震层以上仅发生刚体平动且层间位移较小的同时,各层加速度响应较之对应的抗震结构大幅降低,从而有效地改善了该类结构的抗震性能,保护了上部主体结构.
Through comparing and analyzing whether or not the isolation technique is used for concrete frame structures by using ANASYS,the dynamic responses of the isolation structure in different field conditions and seismic intensities are studied,and the variation laws of the acceleration,displacement and interlayer displacement are analyzed.The study results show that comparing with the results of traditional seismic structures,the acceleration in the upper structure used with the sliding isolation structure is decreased obviously,the interlayer displacement is a little,and the pure friction as well as its residual displacement could not be neglected.All these as mentioned above could provide references for the research of the sliding isolation.
In contrast with the traditional shock-isolation theory and structural vibration theory,the viscoelastic damper which is applied to the energy suspension of structure was introduced.Through analyzing the characteristic,application and principle of viscoelastic damper,the corresponding formulas was deduced and the earthquake effect of the structure under dynamic response was analyzed.Results show that using viscoelastic damper,additional stiffness and damping to structure can be provided.Thus,the dynamic response and shock of structure can be reduce.
