IStructE EC2 (Concrete) Design Manual 9 Foreword The Eurocode for the Design of Concrete Structures(EC2) is likely to be published as a Euronorm (EN) in the next few years. The prestandard (ENV) for EC2 has now been avail-able since 1992. To facilitate its
Concrete Corrosion Protection for Marine Structures Many concrete piers and wharves are in extremely corrosive marine conditions. Piles and pile caps are faced with intermittent exposure to chloride-contaminated salt water. In other areas of the structure it is
High strength, prestressed concrete structural meers also deliver exceptional load-carrying capacity, which can result in smaller sections, longer spans, or both when compared to other structural systems. Total Precast concrete offers many
This second edition of Precast Concrete Structures introduces the conceptual design ideas for the prefabriion of concrete structures and presents a nuer of worked examples that translate designs from BS 8110 to Eurocode EC2, before going into the detail of
Features of the prestressed concrete strand 1.High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, straight, firm connection with concrete. 2.Unbonded and bonded prestressed steel strands have good corrosion resistance and small friction of unbonded tendons, which can be easily bent into curved shapes.
Structural strengthening is the process of upgrading structures to improve performance under existing loads or to increase the strength of structural meers to carry additional loads. The need for structural strengthening is commonly driven by building codes, deterioration, change in use, or deficiencies caused by design and/or construction errors.
