Research Status of Laminated Bamboo
Abstract Bamboo engineering material is a new type of engineering material that is sustainable and environmentally friendly.Bamboo glulam has been gradually used in a large number of building structural components,due to its green environmental protection,corrosion resistance,ability to flexibly control the size and length,and its superior mechanical properties.Today,it is a new and excellent material for strengthening and improving the structure,it also has good development prospects,and it is in line with the national energy conservation and emission reduction concept.The development of modern bamboo structures shows that the modern bamboo structure system will have great potential in the field of civil engineering. This article discusses the research status of bamboo glulam, and introduces the characteristics of bamboo glulam, its manufacturing process, mechanical properties, anti-corrosion treatment, and its reinforcing effect on FRP, and discusses that bamboo glulam will be used as the main building in the future. Materials are the inevitable choice for the overall coordinated and sustainable development of the construction industry.

- 竹集成材的特点及制造工艺
1.1竹集成材的发展历史
竹集成材是当下具有良好应用和推广前景的新型材料，它是一种同于木材又不同于木材的一种特殊的材料。木材长期供应不足因而成为国民经济中的短线物资，因此“以竹代木” 为竹材大量的推广和应用提供了很好的发展机遇。由于竹子生长周期短，且其有着相当大的开发利用价值，因而竹子成为自然界中效能最高的可再生材料。曾在80年代初期~80年代中期，竹材曾面临着竹材积压滞销的局面；1996年以后，随着国家宏观调控政策的实施，“以竹代木”又面临着新的挑战；近年来，随着技术、市场、产品的日渐成熟，竹材的应用又在我国迅速发展起来[1]。
