摘要介紹東海大橋主航道斜拉橋鋼混凝土箱形結合梁的鋼結構部分、混凝土橋面板、鋼混凝土結合部位在海洋環境下耐久性設計特點及採用方案。Beams are researched, and the relation between strains of corroded re - bars and fatigue life of beams are obtained. the main research contents and conclusions are as following : 1. under the fatigue loads, the overstrain of concrete approximately coincidences three stages strain development and accumulation rule, and the mechanical property of concrete is deteriorated
鑒于實際工程中大量存在腐蝕鋼筋混凝土結構承受反復荷載作用，但其力學性能研究不多的問題，本論文進行了銹蝕鋼筋混凝土梁抗彎疲勞試驗，研究了應力比和鋼筋銹蝕率對銹蝕鋼筋混凝土梁抗彎疲勞性能的影響，得出了銹蝕鋼筋的應變與構件疲勞壽命之間的關系曲線，主要研究內容及結論如下: （ 1 ）在循環荷載下，混凝土殘余變形基本符合三階段變形規律，力學性能劣化，疲勞損傷積累。Abstract : durability zonation standard ( dzs ) is proposed to provide useful parameters for durable concrete structure design. it deals not only with the influence of environment on structures, but also with types, functions and importance of structures based on the theory of life cycle cost ( lcc ). first, the basic concept of dzs for concrete structure design is defined. then the basic principles for dzs are established. the factors for zonation according to natural environmental conditions and structural importance are identified. the usefulness of dzs by citing a real application for concrete highway bridges in zhejiang province is demonstrated. finally, durability regulations are provided accordingly to zonation
文摘:混凝土結構耐久性環境區劃標準的目的就是為混凝土結構耐久性設計提供合理的設計參數.混凝土結構耐久性環境區劃標準在結構全壽命周期成本原理基礎上考慮了環境對結構的影響，並將結構的重要性、結構形式和功能等多方面因素一併納入考慮之中.首先給出了混凝土結構設計耐久性環境區劃標準的概念和建立該標準的3個基本原則，其次根據自然環境條件和結構重要性等確定了區劃的主要影響因素，然後以浙江省公路橋梁結構耐久性環境區劃圖的編制為例說明了混凝土結構耐久性環境區劃的可行性與實用性，最後根據區劃圖給出了耐久性區劃標準的若干設計規定Durability zonation standard ( dzs ) is proposed to provide useful parameters for durable concrete structure design. it deals not only with the influence of environment on structures, but also with types, functions and importance of structures based on the theory of life cycle cost ( lcc ). first, the basic concept of dzs for concrete structure design is defined. then the basic principles for dzs are established. the factors for zonation according to natural environmental conditions and structural importance are identified. the usefulness of dzs by citing a real application for concrete highway bridges in zhejiang province is demonstrated. finally, durability regulations are provided accordingly to zonation
