葡萄酒品牌忠诚影响因素的结构方程分析 ——以胶东地区为例

基于胶东地区206个样本，以瑞典顾客满意度指数（SCSB）模型为理论基础，采用结构方程模型，从文化认同、营销感知、产品体验、功能体验4个维度设计11个观测变量探讨影响葡萄酒品牌忠诚的因素。研究表明，4个维度因素对品牌忠诚都有直接或间接的正向促进作用。产品体验直接影响品牌忠诚，文化认同、营销感知、功能体验对品牌忠诚均有直接和间接影响，文化认同是影响葡萄酒品牌忠诚的最主要因素。最后根据研究结果提出建议。     

明星IP驱动的服装品牌产品创新模式研究

目的 针对当下服装品牌与明星IP合作常态化趋势下，明星IP服装同质化严重、服装品牌的投入与产出不断缩小等问题，服装品牌需要进行产品创新以更好地迎合市场提升品牌竞争力。方法 基于明星IP驱动的服装品牌产品创新视角，对产品创新模式分别从核心设计、产品语义设计与产品延伸设计三个方面提出假设，架构“行为—感知—购买意向”的研究模型，然后通过设计消费者调查问卷，对该假设进行实证检验。结果 产品核心设计通过产品感知与品牌感知，显著影响消费者对服装的购买意愿。产品语义设计变量对购买意愿的意向不显著，产品延伸设计对购买意向的影响为正。结论 说明了明星IP核心产品、明星IP语义产品、明星IP延伸产品促进了消费者对服装品牌的购买意愿。

A simplified method for instability and second‐order load effects of framed structures: Story‐based approach

Several building codes such as ANSI/AISC 360‐16 and EC3 EN 1993‐1‐1 require the use of a proper design method to consider instability and second‐order load effect problems for individual system elements and the entire structural system. Various methods are available to assess stability. All of these methods should consider P‐Δ and P‐δ effects (second‐order effects). The following calculation procedures are presented in this study: (a) a simplified method is developed for P‐Δ and P‐δ analysis in regular frames under the effect of constant axial loads to obtain story drifts and end moments; (b) this method can be applied to an entire building or any individual story, that is, story‐based design is possible; and (c) column effective length factors are obtained for individual columns. In addition, design tables are presented.     

Seismic design and performance analysis of buckling‐restrained braced RC frame structures

Due to the stable hysteretic behavior, buckling‐restrained braces (BRBs) have been increasingly adopted in reinforced concrete (RC) frame structures to develop a dual structural system (BRB‐RCF). This study proposed an alternative strength‐based design approach that decomposes the dual BRB‐RCF system into two independent RC frame and BRB system using the BRB‐carrying story shear ratio. The design of RC frame is performed in an integrated manner by considering the BRB postyielding force demands. Three RC frames with five, 10, and 15 stories were employed as prototype structures, and seven story shear ratios ranging from 0.1 to 0.7 were used to generate a total of 21 structural modes. The material usage, maximum axial compression ratio of columns, and elastic interstory drift ratio were compared for different story shear ratios. Nonlinear dynamic analysis of the BRB‐RCFs subjected to 12 ground motions were carried out. The seismic response including the maximum interstory drift ratio, hysteretic energy dissipation ratio, and actual BRB‐carrying story shear ratio were systematically assessed for different design story shear ratios. Based on the considerations of material usage and seismic performance, it is suggested that the design BRB‐carrying story shear ratio should be in the range of 0.3 to 0.5.
