Research on the Ecological Wisdom of Traditional Dwellings of the Liangshan Yi Nationality Based on Regional Climate

As a typical building with ethnic and regional characteristics in southwest Chi-na, its construction skills contain rich local ecological wisdom. The detailed analysis of the climatic and geomorphological features of the Liangshan Yi nationality area shows that the thermal mass effect is the first choice for the passive adjustment strategy of residential dwellings. This study focuses on the typical representatives of traditional dwellings in Meigu County, analyzing the wisdom of ecological construction to improve the thermal mass effects of res-idential buildings at the macro (village), moderate (courtyard), and micro (building unit) levels. Based on this analysis, the study summarizes the “genetic factor library” of the ecological construction mode of traditional Yi residential dwellings. Finally, the measured data of the residential thermal environment and the simulation data of Ecotect software are used to study and judge the logic behind its ecological construction wisdom. The results show that the tradi-tional dwellings of the Yi nationality in Liangshan have six aspects of local en-vironmental knowledge to improve the thermal mass effects performance of buildings. The winter thermal environment of the house is comfortable, and the heat is sufficient;Rammed earth materials in residential buildings have more potent, powerful, and robust thermal mass effects performance than stone slabs and wooden boards.

Urban Spatial Form Optimization Strategies Based on the Principle of Climate Adaptability of Regional Architecture: A Case Study of Traditional Cave Dwelling Villages in Northern Shaanxi Province

A multitude of climate-adaptive design approaches are embedded in regional architecture,which have a positive impact on addressing the deformed development of urban spatial patterns and the dual challenges of climate and resources.This paper examines the principles of climate adaptability embedded in the site layout and spatial organization characteristics of traditional cave dwelling villages in northern Shaanxi Province.The extracted climate adaptability principles are summarized,and the resulting design strategies that are well-suited to the contemporary urban space form are presented.Through analysis,it can be observed that traditional cave dwelling villages in northern Shaanxi are predominantly situated on south-facing slopes in proximity to water at low altitudes.These villages are characterized by compact building groups and east-west development,which is constrained by the elements of mountains and rivers.A two-level street system is generated,comprising streets parallel to the contour line and roadways perpendicular to the contour line.This results in the formation of a courtyard form enclosed by mountains.Such site layout and spatial organization exhibit excellent climate adaptability with regard to heat,ventilation,and wind storage.In light of the aforementioned considerations,the following urban spatial form design strategies are put forth:①the topographic height difference can be exploited to obtain sufficient sunshine;②the group shape can be optimized in order to reduce building energy consumption;③the best orientation of the building can be chosen to take account of both winter and summer conditions;④the height and length can be combined in order to form natural masking;⑤the D/H ratio of streets and roadways should be controlled to achieve a balance between heat gain and cooling of groups;⑥vents should be set appropriately to optimize group ventilation;⑦climate buffers should be established to increase the level of climate response.

Ecological Culture in Traditional Chinese Vernacular Dwellings

Traditional Chinese vernacular dwellings take root in farming culture with profound connotations. Through analyzing ecological thoughts and cultural ideas in traditional vernacular dwellings, this study aims to provide references for the design of modern vernacular dwellings. It is proposed in this study that ① Ecological thoughts of traditional vernacular dwellings include the simple eco-thought of 'human-nature oneness', Fengshui (traditional Chinese ideas hold that the location of a house or tomb is supposed to have an influence on the fortune of a family) theories of 'balance of yin and yang', energy-saving thought of 'making the best use of local advantages'. Traditional vernacular dwellings are mainly constructed according to local conditions, facing the sunny side and water, backing on the shady side and mountains, with local materials and suitable construction structures for local environment and climatic conditions, which enable residents to enjoy warm winter and cool summer, sufficient sunshine, excellent ventilation and heat-proof, wind and humidity proof, that is, a natural ecological living environment. ② Cultural thoughts of traditional vernacular dwellings include the strict and square philosophical ideas as well as harmonious artistic thoughts. Traditional Chinese vernacular dwellings demonstrate morals and ethics by strict and square patterns and strong sense of hierarchy, most of them have definite axes in spatial patterns to show the hierarchy and core of construction groups; abstract patterns of flower, grass, animal or human beings are also often applied in detailed designs, showing esthetic tastes. The formation of traditional Chinese vernacular dwellings has been closely linked with social and cultural factors, living habits, geographical, water and soil, environmental and climatic conditions as well as folk customs, which can provide significant references for the design and reformation of modern new-type vernacular dwellings.

Enhanced strength-ductility synergy in a wire and arc additively manufactured Mg alloy via tuning interlayer dwell time

Strength-ductility trade-off is a common issue in Mg alloys. This work proposed that a synergistic enhancement of strength and ductility could be achieved through tuning interlayer dwell time(IDT) in the wire and arc additive manufacturing(WAAM) process of Mg alloy.The thermal couples were used to monitor the thermal history during the WAAM process. Additionally, the effect of different IDTs on the microstructure characteristics and resultant mechanical properties of WAAM-processed Mg alloy thin-wall were investigated. The results showed that the stable temperature of the thin-wall component could reach 290 ℃ at IDT=0s, indicating that the thermal accumulation effect was remarkable. Consequently, unimodal coarse grains with an average size of 39.6 μm were generated, and the resultant room-temperature tensile property was poor. With the IDT extended to 60s, the thermal input and thermal dissipation reached a balance, and the stable temperature was only 170 ℃, closing to the initial temperature of the substrate. A refined grain structure with bimodal size distribution was obtained. The remelting zone had fine grains with the size of 15.2 μm, while the arc zone owned coarse grains with the size of 24.5 μm.The alternatively distributed coarse and fine grains lead to the elimination of strength-ductility trade-off. The ultimate tensile strength and elongation of the samples at IDT=60s are increased by 20.6 and 75.0% of those samples at IDT=0s, respectively. The findings will facilitate the development of additive manufacturing processes for advanced Mg alloys.
