Structural Shell Analysis
The mathematical description of the properties of a shell is much more elaborate than those of beam and plate structures. Therefore many engineers and architects are unacquainted with aspects of shell behaviour and design, and are not familiar with sufficiently reliable shell theories for the different shell types as derived in the middle of the 20th century. Rather than contributing to theory development, this university textbook focuses on architectural and civil engineering schools. Of course, practising professionals will profit from it as well. The book deals with thin elastic shells, in particular with cylindrical, conical and spherical types, and with elliptic and hyperbolic paraboloi...
Stringer-Panel Models in Structural Concrete
Structural concrete designers nowadays distinguish between B-regions (named after Bernoulli beam theory) and D-regions (D standing for ‘disturbed’). They are all familiar with B-regions, but less acquainted with the expertise required for D-regions. To design D-regions, the Strut-and-Tie Model (STM) is usually applied, a model laid down worldwide in structural codes of practice. The Stringer-Panel Model (SPM) recommended here is a companion method to the STM, with the advantage of being suitable for different load cases and reversed loading. This being so, the SPM is suitable for linear-elastic analyses where durability is a key consideration, but also suits structural design for contexts of cyclical seismic activity. Finally, this book sets out how structural engineers who prefer the STM can nevertheless apply the SPM to determine a proper strut-and-tie model.
Plates and FEM
The Finite Element Method, shortly FEM, is a widely used computational tool in structural engineering. For basic design purposes it usually suf ces to apply a linear-elastic analysis. Only for special structures and for forensic investigations the analyst need to apply more advanced features like plasticity and cracking to account for material nonlinearities, or nonlinear relations between strains and displacements for geometrical nonlinearity to account for buckling. Advanced analysis techniques may also be necessary if we have to judge the remaining structural capacity of aging structures. In this book we will abstain from such special cases and focus on everyday jobs. Our goal is the worl...
Concrete Fracture
The study of fracture mechanics of concrete has developed in recent years to the point where it can be used for assessing the durability of concrete structures and for the development of new concrete materials. The last decade has seen a gradual shift of interest toward fracture studies at increasingly smaller sizes and scales. Concrete Fracture: A Multiscale Approach explores fracture properties of cement and concrete based on their actual material structure. Concrete is a complex hierarchical material, containing material structural elements spanning scales from the nano- to micro- and meso-level. Therefore, multi-scale approaches are essential for a better understanding of mechanical prop...
Computational Mechanics ’88
The aim of this Conference was to become a forum for discussion of both academic and industrial research in those areas of computational engineering science and mechanics which involve and enrich the rational application of computers, numerical methods, and mechanics, in modern technology. The papers presented at this Conference cover the following topics: Solid and Structural Mechanics, Constitutive Modelling, Inelastic and Finite Deformation Response, Transient Analysis, Structural Control and Optimization, Fracture Mechanics and Structural Integrity, Computational Fluid Dynamics, Compressible and Incompressible Flow, Aerodynamics, Transport Phenomena, Heat Transfer and Solidification, Electromagnetic Field, Related Soil Mechanics and MHD, Modern Variational Methods, Biomechanics, and Off-Shore-Structural Mechanics.
DIANA Computational Mechanics ‘94
Advances in computational mechanics can only be achieved on the basis of fruitful discussion between researchers and practising engineers. This has been achieved in the present publication, which contains all the papers presented at the first International DIANA Conference on Computational Mechanics. Nearly all papers show the results of calculations achieved with the DIANATM Finite Element System. Broadly, the book follows the line of research from the material level, via the element level, to the structural level. But it should be emphasised that much current research passes from one level to the other, and such an interaction is also reflected here. The following domains are treated: (hyper)elasticity, (visco)plasticity and cracking; (enriched) damaging continua models; material experiments vs. computational models; stochastic approaches; fluid--structure interactions; element technology; geometrical nonlinearity and structural instability; nonlinear dynamics; solution procedures.
Modelling and Analysis of Reinforced Concrete Structures for Dynamic Loading
A comprehensive review of the material behavior of concrete under dynamic loads, especially impact and impuls, opens the volume. It is followed by a summary of the various analytical tools available to engineers interested in analyzing the nonlinear behavior of reinforced concrete members for dynamic load. These range from relatively simple and practice-oriented push-over analysis to sophisticated layered finite element models. Important design-related topics are discussed, with special emphasis on performance of concrete frames subjected to seismic loads. The significance of modern software systems is recognized by including extensive examples. For readers not current in dynamic analysis methods, an appendix contains a review of the mathematical methods most commonly used for such analysis.
