| 1 | Concurrent topology optimization for minimization of total mass considering load-carrying capabilities and thermal insulation simultaneously显示文摘The present work introduces a novel concurrent optimization formulation to meet the requirements of lightweight design and various constraints simultaneously.Nodal displacement of macrostructure and effective thermal conductivity of microstructure are regarded as the constraint functions, which means taking into account both the loadcarrying capabilities and the thermal insulation properties.The effective properties of porous material derived from numerical homogenization are used for macrostructural analysis. Meanwhile, displacement vectors of macrostructures from original and adjoint load cases are used for sensitivity analysis of the microstructure. Design variables in the form of reciprocal functions of relative densities are introduced and used for linearization of the constraint function. The objective function of total mass is approximately expressed by the second order Taylor series expansion. Then, the proposed concurrent optimization problem is solved using a sequential quadratic programming algorithm, by splitting into a series of sub-problems in the form of the quadratic program. Finally, several numerical examples are presented to validate the effectiveness of the proposed optimization method. The various effects including initial designs, prescribed limits of nodal displacement, and effective thermal conductivity on optimized designs are also investigated. An amount of optimized macrostructures and their corresponding microstructures are achieved. | Kai Long Xuan Wang Xianguang Gu | 2018 | Acta Mechanica Sinica2018，34，2： | 7 |
| 2 | The Research on the Evaluation and Optimization of the Traditional Dwelling Conservation Practice:A Case Study of Cheng Zhi Hall Restoration Project within Hongcun显示文摘Hongcun is the World Cultural Heritage which is a Traditional Village in China,and Cheng Zhi Hall is the most important traditional dwelling within Hongcun.In December 2010,Yi County Cultural Relics Bureau commissioned Anhui Provincial Cultural Relics Protection Center to complete the Restoration Plan of Cheng Zhi Hall,Hongcun Village,Yi County,Huangshan City,Anhui Province,and carried out the actual restoration project from 2015 to 2018.However,by the evaluation of the restoration plan and project of Cheng Zhi Hall,many problems are found such as that the description of restoration measures is rough,the restoration drawings are not clearly marked,and the restoration practices are lack of the theoretical support and so on.Therefore,the aim of this research is to sort out the existing problems,and through the comparative study of the relevant Italian cases,putting forward the optimization strategies of the plan and practice of traditional dwelling conservation practice in China. | Tingshen Li Minghao Zhang Xianguang Gu | 2020 | Journal of Architectural Research and Development2020，4，4： | 0 |
