The long-term safety and serviceability of concrete structure should be considered in its life cycle, including planning, designing, construction, management and maintenance. It is essential to consider strength, deformation and durability of concrete structure in the design procedure. However, a large proportion of Taiwan's engineering practice only considers strength and neglect deformation and durability, in other words, we only discuss structure’s design strength and neglect effects caused by shrinkage & creep, both of which have a huge impact on safety and serviceability of structures.

After comparing Taiwan’s shrinkage & creep data to foreign data, we discovered several obvious differences, such as the composition of mix design proportion, material characteristics and weather conditions. We realized that we can’t apply foreign prediction models unless certain modifications were adapted. For the reasons mentioned above, this research collects shrinkage & creep data from the past 4 decades and present a modified prediction model that is suitable for Taiwan’s concrete that can be easily used by scholars and engineers.

混凝土結構物之規劃、設計、施工、管理及維護之生命週期均需考慮混凝土結構物長期安全與服務性。其設計考慮因素，應包括在混凝土強度、變形及耐久性。然而，在台灣工程實務上多僅考量強度，輕忽混凝土之收縮與潛變等所造成安全及服務性的影響。

國內外的混凝土配比資訊，材料及氣候條件差異明顯，使用國外之規範難以掌握，因此需發展出一套台灣獨有的收縮及潛變資料庫，並回歸出一套適用台灣的收縮及潛變公式模型以利於工程界及學術界使用。
