A multiple-step beams model was established to analyze the static stiffness characteristics of the double parallel four-bar mechanism with right angle flexible hinges based on the symmetry of the structure. Formula for calculating the static stiffness was derived by applying singularity function. On the basis of this analysis, the factors influencing the stiffness performance of the double parallel four-bar mechanism were studied from its geometric parameters, and the theoretical model was verified by finite element method.

Pugin, Ruskin, and Viollet-le-Duc are representative of the Gothic Revivalism theorists who gave impetus to the Gothic Revival by their work. A review of the literature shows that the superiority of the Gothic Style derived from different kinds of interpretation, such as religious spirit, social reform, esthetic taste, practical function, economic considerations, and construction technology. These interpretations originated in different kinds of values. The main reason why these theorists promoted the revival of the Gothic Style came from personal factors. Their differences in personal values illustrated that the Gothic Revival was the result of various motive forces which gathered together.

普金、罗斯金以及维奥列-勒-杜克(Viollet-le-Duc)三位建筑理论家是十九世纪推动哥德复古的主要代表人物，三者均利用个人的著作传达他们对哥德样式的支持，根据相关文献的探讨，哥德样式的优越性来自於个人的诠释观点，具有代表性的包括：精神信仰、社会改革、美学品味、实用机能、经济考量与工程技术，不同的诠释方式来自於不同的价值观，这说明了理论家鼓吹哥德样式的主要因素是来自於个人因素，个人价值观的差异性也说明了哥德复古邉拥漠a生是各种推动力量汇集折冲的结果。
