EVALUATION OF LONG‐TERM BEHAVIOUR OF COMPOSITE TIMBER‐CONCRETE STRUCTURES ACCORDING TO EC
研究了木-混凝土组合梁的长期行为，考虑蠕变、粘弹性、收缩等流变现象，依据欧洲规范EC5和EC2进行极限状态和正常使用状态验证。
The objective of this work is the investigation of long‐term behaviour of composite timber‐concrete beams. Both ultimate and serviceability limit states have to be satisfied according to modern design codes, such as Eurocode 5. Because of the rheological phenomena such as creep, time‐dependent (viscoelastic) creep, mechano‐sorptive (moisture change) creep and shrinkage/swelling that occur in the component materials, stress and strain distribution changes in time. The rheological phenomena have to be taken into account for long term verifications. This paper presents the review of the evaluation of long term behaviour of composite timber‐concrete beams according to European design codes EC5 and EC2.
