部分包覆钢-轻骨料混凝土组合长柱的自重较部分包覆钢-普通混凝土组合长柱的自重可减少15%以上，在装配式建筑中的应用前景广阔。为研究其轴压性能，建立了有限元分析模型，并在现有试验验证有限元模型可靠的基础上，对比分析了轻骨料混凝土与普通混凝土的材料属性及构件力学性能的差异。结果表明，采用相同强度的普通混凝土组合长柱的承载力预测轻骨料混凝土组合长柱的承载力是偏于危险的。之后，研究了轴压作用下该构件的全过程受力机理和破坏模式，探讨了材料强度、长细比、含钢率等参数对构件轴压性能的影响规律，验证了现有规程对计算该类组合长柱轴压承载力的适用性。研究成果可为部分包覆钢-轻骨料混凝土组合构件的理论研究和设计提供参考。

With the improvement of living standards and the enhancement of environmental awareness, the demand for adhesives grows rapidly. In particular, biomass adhesives have attracted widespread attention, Biomass adhesives are natural adhesives prepared from biomass and its derivatives of animals, plants and microorganisms. Although the biomass adhesives have the advantages of wide source of raw materials, non-toxic, environmental friendliness and degradability, the poor mechanical properties, low water resistance, and easy to be at- tacked by bacteria hinder the practical application of biomass adhesives. By grafting, crosslinking, filling acid treatment and other modifications of these biomass raw materials. their shortcomings can be improved, which enables their application in wood, food, medical treatment, cultural relics restoration and other fields. In this review, the preparation, application and the most recent research status of the adhesives from the biomass of animal and plant proteins, lignin, chitosan, tannin, cellulose and starch are included. The future development trend of biomass adhesives was also reviewed. This review will provide reference for the further development and application of biomass in the field of adhesives.

Black soldier fly is a worldwide resource insect, which is often added to animal feed because of its rich contents of protein, fatty acids, chitin, chitosan and antibacterial peptides. In addition, because its larvae live in saprophytic life, it can transform the treated organic matter into the nutrients it needs at the maximum efficiency. In recent years, it is often used in the harmless treatment of feces or waste, and it has become a hot spot of concern. The overview of the application research of black soldier fly larvae and the research status of larvae in feed application were reviewed, harmless treatment and challenges were discussed in detail. We hope to provide literature reference for the basic research and subsequent industrial production application of black soldier fly larvae. [ABSTRACT FROM AUTHOR]
