最近，在RWTH亚琛大学，建造了一个由纺织钢筋混凝土(TRC)制成的屋顶壳，TRC是一种由细粒混凝土和碳纤维形式的高强度、耐腐蚀的纺织钢筋组成的复合材料。薄壁TRC壳体结构令人印象深刻地展示了这种创新复合材料的承载能力。本文讨论了用喷射混凝土制作TRC壳体、钢筋布设的概念以及在预制混凝土柱上安装壳体等施工中的实际问题。关于TRC壳体承载性能的设计、评估和数值模拟的问题，载于配套文件(第二部分)。
At RWTH Aachen University recently, a pavilion was constructed with a roof shell made of textile-reinforced concrete (TRC), a composite material consisting of a fine-grained concrete and high-strength, non-corroding textile reinforcement in the form of carbon fibres. The thin-walled TRC shell structure demonstrates impressively the loadbearing capacity of this innovative composite material. The present paper discusses the practical issues concerning the construction, such as the fabrication of the TRC shells using shotcrete, the concepts developed for the arrangement of the textile reinforcement and the erection of the shells on top of the precast concrete columns. The issues concerning the design, assessment and numerical simulation of the loadbearing behaviour of TRC shells are presented in the companion paper (Part II).
