| 1. | Cyclic tests of semirigid end - plate connections in multi - story steel frames 多层钢框架半刚性端板连接的循环荷载试验研究 |
| 2. | In order to satisfy anti - seismic design commend , ductility has been needed in multi - story and high - rise buildings 地震区的多层钢框架结构需要具有较好的延性以满足抗震设计的要求。 |
| 3. | ( 2 ) mechanics model of multi - layers metal ring and the model of transmission slip ratio were established ( 2 )建立了cvt传动多组件的力学模型,解析了多层钢带受力和钢带传动滑移率。 |
| 4. | Steel structures have been widely used in civil engineering as a result of the advantages . one of dominating structural systems is steel frame 钢结构以其明显的优势在各类工程中得到越来越多的应用,多层钢框架结构房屋已成为建筑业重点推广的十大技术之一。 |
| 5. | Beam column connections experienced a great deal of brittle fracture phenomenon in northridge earthquake and hyogoken - nanbu earthquake which indicated that connection performance is very important for steel frames 发生在美国北岭和日本阪神地震都发生不同程度的梁柱节点脆性破坏,可见梁柱节点在多层钢框架结构抗震设计中占有非常重要的地位。 |
| 6. | To research connection behavior under seismic action in multi - story steel frames and to improve ductility as well as anti - seismic ability in case brittle fracture has great theoretical value and project significant in building construction 因此,钢框架梁柱节点抗震性能的研究对多层钢框架改善结构延性、防止节点发生脆性破坏、提高结构抗震能力有着重要的理论意义和工程意义。 |
| 7. | Fourthly , in term of the basal theory of the reliability of structural system , the basal system assessing the reliability of the multiplayer steel frame is put forward and established ; the trichotomy that is a way basal system assessing the reliability of the steel frame according as the route of transferring forces and assessing the reliability of the steel frame of coke made by dry flameout , which can improve the the assessing ways on the reliability of our country criterion and add the assessing ways on the reliability of the multiplayer steel frame 第四,根据结构体系可靠性的基本原理,提出和建立了多层钢框架可靠性评定的基本体系,提出按传力路径评定钢框架体系可靠性的三分点法,并对干熄焦钢框架的可靠性进行了完整的评定,它们可改进现行国家标准的可靠性评定方法,并为增加多层框架的可靠性评定方法提供参考。 |
| 8. | After analyzing the maximum lateral displacement , the internal force and the steel dosage of every kind of structure , it can be concluded that the lateral - resisting mechanics performance of the shear model framework is satisfactory . the internal force of the whole structure is reformed remarkably and the shear model framework is advantageous concerning the steel dosage 通过对各种结构形式最大侧移、结构内力及耗钢量的比较,可以看到将抗剪单元用于多层钢框架结构之后,框架的抗侧移性能满足我们对多层钢结构的要求,同时框架的内力得到了大大的改善,在耗钢量方面也有很大的优势。 |
