Abstract
A full interactive computer program; TED 1, is presented for the analysis and design of a wide variety of R.C. structures in three dimensions, based on the Egyptian code of practice, ECOP. A finite element method with six degrees of freedom nodal-point-displacement system, is used for linear elastic analysis. The structure is idealized simply, for the user, as an assemblage of the two’ available elements: two-nodes beam-column element and up to ten¬ Nodes rectilinear plate elements. Further, these elements are segregated, by the program, to Smaller ones. The beam-column element is divided to four two-node beam-column elements. The plate element is divided to a number of six-node triangular plate elements, equal to twice The number of plate sides. Each triangular element is divided to four coincident triangles. all structural elements are included in the overall stiffness matrix enabling integrated Behavior of the structure. Both bending and membrane stiffness of plates are considered. static (or equivalent static)and time-independent dead and live loads of the forms of Gravity, pressure, wind, earthquakes, support movements, and nodal restraints are the loads and effects considered in this study. Most of these loads; wind, seismic, and own weight of Members And Partition walls, Are Evaluated Completely By The Program When Specified. Analysis is performed Once For Each Of The Specified Cases Of Loading Using The Service Loads. Results of the analysis for the different cases of loading are factored, by the program, Using the convenient load factors all the possible load combinations are applied on their corresponding straining actions, the extreme and absolute values of the six straining actions Are extracted at each node of the segregated assemblage utmost twelve groups of six compatible straining actions at each node are prepared and passed internally to design phase. Limit state design method provided in ECOP is used in design. The ultimate strength of a section is evaluated considering the idealized stress-strain curves for steel and concrete Along with equilibrium and strain compatibility conditions. Design procedures are established basically for bi-axial straining actions, while those; uni-axial and pure are special cases. The final dimensioning of a section in an element is the envelope of the results of as many design processes as the possible groups of simultaneous straining actions on that section. Elements; beams, columns, plates, and R.C. walls, arc completely designed according To the provisions in ECOP, along with innovated methods to allow for-the design in three Dimensions Economical and practical factors besides optimization principles are stressed on in design criteria
