Adaptively prestressed concrete structures
Passive structures react effectively to only one dominant loading condition. Adaptive structures in contrast can deal with multiple loading conditions and unanticipated events at the same time. Truly adaptive civil structures do not exist. Concrete structures can be made adaptive through variable …

Optimization of Reinforced Concrete Structures
… is presented for the design of reinforced concrete structures. The design variables are the overall depth, effective depth and width of members, and area of longitudinal reinforcement. In addition, the details such as the amount of web reinforcement and cutoff points of longitudinal …

Flexible formwork for concrete structures
Concrete, our most widely used construction material, is a fluid that offers the opportunity to economically create structures of almost any geometry. Yet this unique fluidity is seldom capitalised on, with concrete instead being cast into rigid prismatic moulds to create high material use …

Computer Design of Reinforced Concrete Structures.
I. INTRODUCTIONA. ICES is an acronym for Integrated Civil Engineering System, a major computer system dedicated to the advancement of the teaching and practice of civil engineering (7). The system was developed at the Massachusetts Institute of Technology during the mid 1960s. It is a large scale …

Life cycle cost design of concrete structures
… based procedure for the design of reinforced concrete structural elements is presented in this thesis. The design procedure attempts to integrate structural performance and durability together with economic cost optimization into the structural design process. The evaluation of structural …

Techniques of seismic retrofitting for concrete structures
… about the vulnerability and design practice of structures, especially concrete structures. Design codes have being updated to include seismic previsions but structures build before 1971 have to be retrofitted. The focus of this paper is concrete structures. Surveys done after earthquakes have …

Multiple earthquake effects on degrading reinforced concrete structures
… loadings. Deterioration effects are obvious in structures that experienced main-shock aftershock earthquake sequence and were able to withstand the main-shock however they collapsed in the smaller aftershock. Limited research has addressed the seismic behavior of structures subjected to multiple …

Ductility and deformability of FRP strengthened reinforced concrete structures
There are many structures in need of strengthening and upgrading and the need for this is due to a number of factors:<br/><br/>• Structural deterioration over time<br/>• Traffic volume increases<br/>• Increases in allowable maximum vehicle weights<br/>• Poor maintenance<br/>• Poor construction …

Experiments to study seismic drift of reinforced concrete structures
Earthquake-simulation tests of fifteen reinforced concrete single-degree-of-freedom systems were made to provide benchmark data for studying nonlinear drift response. Test variables included strength and initial period of the specimen, and frequency content and intensity of simulated earthquake …
