Concrete Engineering Handbook [antikvár]

PREFACEThis handbook aims to present in one volume fundamental and practical information in the field of reinforced concrete that may be useful to practicing civil and structural engineers and particularly those interested in the design and construction of buildings and bridges and related structures.In order to provide space for the maximum coverage of material, this handbook was planned for those who have been professionally trained either formally or through practical experience. Thus, with a basic understanding of structural mechanics and of reinforced concrete assumed, it was possible for the contributors to go right to the heart of their subjects.Every designer must be thoroughly conversant Avith the materials to be called for in his designs. He must understand the field problems of cast-in-place or of precast construction and the latest thinking or codification with respect to the problems of earthquake-resistant structures, loadings for bins, and design of tall chimneys. To be helpful, summaries on the subjects of prestressed concrete, of indeterminate structural theory, of member torsion, and of concrete skin structures are also included as well as material on earth pressures, foundations, and pavement design.A large section has been devoted to the design of building frames with many helpful tables including (1) those giving the moment of inertia of selected size beams and arrangement of reinforcing for the more rapid first trial or final design of desired sizes, (2) selected size columns and arrangement of reinforcing for given loadings, and (3) several arrangements of footings to carry given column loadings.The design of simple and continuous span bridges, rigid frames, and arches, with related material on retaining walls, abutments, piers, and floor slabs, all well illustrated, covers several sections and completes the presentation in this handbook.So much has been written on the subject of reinforced concrete, and for so many years reinforced concrete has been used in the construction of all kinds of structures, that we tend to take source material for granted or lose track of its origins. A conscientious effort has been made throughout this handbook to give credit where credit is due. Where appropriatevii
