对结构创新的动力、前提和途径进行了详细阐述.指出人类社会的需求、建筑功能的不断求新、求变,成为结构创新的动力;有效地采用各个学科的先进技术,是结构创新的前提.在结构创新的途径中,结构材料的发展为结构创新提供了基础,结构体系的发展是结构创新的核心,结构功能的发展为结构创新提供了新的需求,结构施工技术的发展使结构创新得以实现,结构理论的发展为结构创新提供了理论基础,结构试验的发展则为结构创新提供了试验验证与保障.从一个结构工程创新所体现的方面、涵盖的内容和达到的效果等三个方面,对结构创新进行了科学界定.
This paper presents a detailed illustration of the structure innovation(SI)in terms of its motivations, premises and approaches. The demands of human society and the continuous changing of architectural function motivate the structure innovation, and the advanced technologies of different disciplines lay a good foundation for structure innovation. Some imponant approaches to SI are also given. The development of structural material, system, function, construction, theories and tests are proposed to be the basis, the core, the new requirement, the realization, the theoretical basis and the validation of SI, respetively. At last, a scientific definition of SI is given from the perspective of its reflection, contents and effects involved in a project.
