IPS are demountable and their components have the potential to be used and reused in different structures and configurations. This paper explores the applicability of birch plywood panels, which are characterized by a high surface hardness, for this type of structural system. Experimental tests were conducted to determine the mechanical properties of birch plywood plates. Moreover, IPS connections with different geometrical properties were investigated for two different load exposures: bending and rotation. The characteristics under bending exposure are influenced by the orientation of the face-veneers. For the rotational load exposure, very small strength and stiffness properties have been identified. A linear elastic finite element model is presented that shows a wide agreement with the test results. The study serves as an initial probe into the performance of IPS structures at the component level. Various aspects that are relevant for the design of IPS, such as the assembly, the accuracy and challenges regarding digital fabrication, the durability, and the structural performance are discussed.","PeriodicalId":34964,"journal":{"name":"International Journal of Space Structures","volume":"36 1","pages":"155 - 163"},"PeriodicalIF":0.0,"publicationDate":"2021-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/09560599211022219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45179138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to reduce the adverse effect of hanger forces, and avoid the construction of complex finite element theoretical model, an optimization method based on adaptive genetic algorithm with MATLAB and Nastran co-simulation is proposed. Then, the hanger forces are optimized, and the deployable structure deformation has been reduced 49%.

The equivalent finite element modeling of such structures is initially presented through the implementation of modal analysis via the three-layered sandwich theory. Subsequently, the computational results are validated by carrying out an experimental modal testing. In addition, sensitivity analysis based upon design of experiments and parameters correlation, is executed for the sake of selecting the most appropriate design parameters for the optimization problem. Finally, finite element model updating of a honeycomb sandwich plate is thoroughly introduced using three optimization algorithms including genetic algorithms, adaptive-multiple optimization, and response surface method. A good agreement between the previously-mentioned optimization algorithms is obtained. Meanwhile, response surface method and its related design of experiments tool succeed in avoiding such time-consuming process and reduce the involved computational expense with an acceptable accuracy.","PeriodicalId":34964,"journal":{"name":"International Journal of Space Structures","volume":"36 1","pages":"105 - 116"},"PeriodicalIF":0.0,"publicationDate":"2021-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/09560599211001683","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42815827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting space grids can be deployed by means of joints arranged on the bars that have a self-locking mechanism which is engaged in the final open position. This configuration overcomes the significant buckling that is characteristic of deployable structures with through-bolted joints.

(1) Building up a three-dimensional formwork by inflating a two-dimensional membrane bag covered with ropes anchored to the snow-ice foundation ring. (2) Covering the formwork with a thin saturated snow layer of less than 1 cm thickness by blowing milled snow with a rotary snow blower and spraying water with an adjustable nozzle, and letting it freeze naturally at temperatures below −10°C. (3) Repeating (2) until shell thickness reaches to the design thickness, then removing the bag and ropes for reuse. A number of ice shells were constructed as temporary winter structures while improving the construction technique through the repeated construction experiences. Based on the field experiments of 10–30 m ice domes (“Xm ice dome” means the ice dome constructed by using Xm diameter of circular membrane bag in the formwork before inflation) which measured the deflection and temperature under long term period after the completion and further observed the behavior of the collapse, it was recognized that understanding the creep behavior is extremely important for evaluating the structural safety of the ice shell.","PeriodicalId":34964,"journal":{"name":"International Journal of Space Structures","volume":"36 1","pages":"26 - 36"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/0956059920981867","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49540663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method, known as Ice Formwork, serves in production of ultrathin lightweight architectural elements – a novel design typology that has emerged with the development of High-Performance Fibre-Reinforced Concrete (HPFRC), and helps to reduce cement consumption, adopt digital fabrication processes, and increase design flexibility. In practice, however, this production employs suboptimal methods of mould-making, using petrochemical or engineered wood products for single-use moulds, entailing excessive amounts of non-recyclable waste. The current work builds on the research and development of a novel production method Ice Formwork facilitated through single-use moulds made of artificially frozen water. Previously published work on the subject has covered topics such as cement hydration at subfreezing temperature, subtractive digital processing of ice and a case of practical application illustrated with the production of a prototype of a lightweight façade rain screen. Yet, since artificial refrigeration and processing of large amounts of water is essential for Ice Formwork production, the environmental performance of this method requires a thorough examination. Thus, the current piece of work attempts to address two major issues, namely: (1) Energy consumption of industrial refrigeration in production of Ice Formwork. (2) Changes in water mineral content after a cycle of Ice Formwork concrete production. For both topics, the research work required development of an original experimental methodology. This aspect has been given the great attention and required development of new technical solutions on many levels. Further research and development is needed to come to a comprehensive environmental assessment, and the results of the current study merely provide a preparatory overview that can help to orient and properly set the objectives for the following research stages.","PeriodicalId":34964,"journal":{"name":"International Journal of Space Structures","volume":"36 1","pages":"78 - 87"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/09560599211001755","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47229130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Afterwards, combining the simulations of solar radiation and CFD, the numerical simulation of sublimation distribution on the surface of were realized by programming in Grasshopper platform. During sublimation, the thickness of the ice composite shell decreases by 0.38 mm every 10 days and the sublimation rate on the sunny side was 1.7 times that on the shady side.
