［摘要］木材具有綠色環(huán)保、輕質(zhì)美觀等諸多優(yōu)點，在我國的應(yīng)用逐漸增多，空間結(jié)構(gòu)是其中一種結(jié)構(gòu)形式。木空間結(jié)構(gòu)主要可以分為木空間網(wǎng)格結(jié)構(gòu)和木空間張拉結(jié)構(gòu)。以一些典型木空間結(jié)構(gòu)為例，綜述了木空間結(jié)構(gòu)在形態(tài)分析、數(shù)值模擬、長期荷載作用下性能、節(jié)點研究、可靠性研究等幾方面的現(xiàn)狀。提出了木空間結(jié)構(gòu)研究需要解決的關(guān)鍵問題，包括材料本構(gòu)模型的建立與選用、木材在長期荷載作用下的蠕變問題、試驗研究和數(shù)值模擬方法、結(jié)構(gòu)動力特性和動力響應(yīng)以及結(jié)構(gòu)體系的可靠性研究等。［關(guān)鍵詞］木結(jié)構(gòu); 空間結(jié)構(gòu); 數(shù)值模擬; 長期荷載; 研究現(xiàn)狀中圖分類號：TU366.2 文獻標識碼：A 文章編號：1002-848X(2016)12-0103-07
State-of-the-art and key research topics of timber spatial structuresHe Minjuan, Dong Hanlin, Li Zheng(College of Civil Engineering, Tongji University, Shanghai 200092, China)Abstract: Timber has many advantages including environmental-friendly, low self-weight and nice-appearance. Applications of timber structures in China has been growing. Spatial structure is one of the suitable forms of timber structures. Timber spatial structures can be divided into two categories: timber reticulated spatial structures and timber tensile structures. A broad state of the art review of timber spatial structures on form-finding, numerical simulation, long-term performance, joint performance and reliability analysis was presented. Several key research topics on timber spatial structures to be further explored were identified and discussed. These topics include the construction and application of constitutive law of the material, creep under long-term loading, experimental study, numerical simulation mothod, dynamic properties and response, system reliability assessment of the structure.Keywords: timber structure; spatial structure; numerical simulation; long-term loading; state-of-the-art
