多维多点激励下大跨度空间钢结构的抗震研究进展
摘要
大跨度空间钢结构作为重要的公共设施,其安全性问题直接关系着国计民生,随着大跨度空间钢结构理论与实践经验的逐渐成熟和完善,其跨度也在逐渐增大。地震载荷作用下,在空间结构设计中考虑地震动的多维多点输入变得十分必要。本文对大跨度空间钢结构多维多点输入抗震的研究现状进行了系统的综述和总结,阐述并评价了现行大跨度空间钢结构考虑多维多点输入的3种抗震计算方法,即时程分析法、随机振动分析法和反应谱法。最后,对今后空间钢结构仍需要进一步研究的问题提出了建议和展望。
As public facilities,the safety of large-span space steel structures is of vital importance to the nation's economy and the people's livelihood.With the development and improvement of structural theories and practical experience of spatial structures,their spans grow gradually.Hence,it is necessary to take multi-dimensional and multi-support excitations into consideration.A state-of-the-art review on seismic design of space structure is carried out.Three earthquake resistant design methods are reviewed,i.e.time-history method,stochastic vibration method and response spectrum method.Finally,some suggestions,which need further investigations,are presented and reviewed for the multi-support problems in the context of space structures.
