Abstract

The purpose of the paper is to share the experience in application of Eurocode 8. Following the existing framework of the European standard two engineering development of two specific topics are proposed. First deals with modelling the seismic action aiming to take into account spatial variability of the seismic action. It is proven that the inclusion of rotational components may influence the action effects and the results provide unsafe design. Evaluation is carried out through response spectrum method. The second topic studies the use of performance based seismic design as a tool to prove the need for seismic strengthening and verification of the benefit. Both target and actual capacity spectra are compared to make assessment of the lateral resistance of existing and strengthened structure. Insufficient elastic stiffness and insufficient yield strength are considered as the most typical situations frequently met in the design practice and which can be settled by seismic strengthening. Discussions and conclusions concerning the philosophy of the assessment procedure are presented.

欧洲法规8:为改进和安全设计使用有利配方

本文的目的是分享欧洲规范8的应用经验。在现有的欧洲标准框架下，提出了两个具体的工程开发课题。首先对地震作用进行建模，以考虑地震作用的空间变异性。结果表明，旋转构件的加入会影响作用效果，设计结果不安全。通过响应谱法进行评价。第二个课题研究了利用基于性能的抗震设计作为工具来证明抗震加固的必要性和效益验证。将目标容量谱和实际容量谱进行比较，对既有结构和加固结构的横向抗力进行评估。弹性刚度不足和屈服强度不足是设计实践中经常遇到的最典型的情况，可以通过抗震加固来解决。提出了有关评估程序哲学的讨论和结论。
