STOCHASTIC STRUCTURAL DYNAMICS APPLICATION OF FINITE ELEMENT METHODS
Author(s)/Editor(s): Cho W. S. To Professor of Mechanical Engineering University of Nebraska-Lincoln, US | Size: 12.84 MB| Format:PDF| Publisher: WILLY
The parallel developments of the finite element methods (FEM) in the
1950's [1, 2] and the engineering applications of the stochastic processes in the 1940's [3, 4] provided a combined numerical analysis tool for the studies of dynamics of structures and structural systems under random loadings. There are books on statistical dynamics of structures [5, 6] and books on structural dynamics with chapter(s) dealing with random response analysis [7, 8]. In addition, there are various monographs and lecture notes on the subject. However, a systematic treatment of the stochastic structural dynamics applying the FEM seems to be lacking. The present book is believed to be the first relatively in-depth and systematic treatment of the subject that applies the FEM to the field of stochastic structural dynamics.
Before the introduction to the concept and theory of stochastic quantities
and their applications with the FEM in subsequent chapters, the two FEM
employed in the investigations presented in the present book are outlined in this chapter. Specifically, Section 1.1 is concerned with the derivation of the
temporally stochastic element equation of motion applying the displacement
formulation. The consistent element stiffness and mass matrices of two beam elements, each having two nodes are derived. One beam element is uniform and the other is tapered. The corresponding temporally and spatially stochastic element equation of motion is derived in Section 1.2. The element equations of motion based on the mixed formulation are introduced in Section 1.3. Consistent element matrices for a beam of uniform cross-sectional area are obtained. This beam element has two nodes, each of which has two degrees-of-freedom (dof).
This beam element is applied to show that stiffness matrices derived from the displacement and mixed formulations are identical. The incremental variational principle and element matrices based on the mixed formulation for nonlinear structures are presented in Section 1.4. Section 1.5 deals with constitutive relations and updating of configurations and stresses. Closing remarks for this chapter are provided in Section 1.6

Dynamics of Structure and Foundation – A Unified Approach 1. Fundamentals

1.1 WHY THIS BOOK
It is said that authorship of any kind is a tremendous boost to one’s ego. Readers, who would care to go through these pages, can be rest assured that this book has not been written to gratify one’s ego trip.
Reason for its birth has been our deep-rooted concern on the way profession of engineering and especially civil engineering is going – in terms of teaching and practice.
Civil Engineering is perhaps the oldest profession amongst the realms of technology, which has been practiced by human being from the early dawn of civilization. It is also indeed a fact that umpteen numbers of books have been written addressing various topics on Civil and Structural engineering from the time of Galileo (1594) till date. So what made us write this book when many of the things mentioned herein may or may not be available in other literature?
The reason for its birth can be attributed as follows:Civil engineering community in India, in spite of making a lot of progress, very few
authors have addressed the topics that we have tried to cover under one platform.
Topics related to structural and soil dynamics that are taught in the universities or referred to in design offices are still dependent on very limited number of books1, or code of practices (often outdated) or research papers not readily available to an average student/engineer.
Finally, in last two decades we have seen a very peculiar trend and that which has affected the profession globally, and could have a long lasting influence on it.
If we look around the world in terms of books published in civil engineering in the last two decades (1980–2000) it will be observed that unlike the period 1960–70 almost all books have been authored by academicians where practicing engineers rarely contributed! Whatever could be the reason for this apathy from engineers in the industry the point remains that students coming out of engineering institutes, unlike 30 years ago
are being exposed minimally to practice as prevalent in industry.
And this we believe is creating a serious gap in engineering education. Till such times practicing engineers are encouraged like in developed countries to participate in teaching we are fearful that engineering especially civil engineering will metamorphose into more an advance course in mathematical physics rather than a scientific art where theory is honed by intuitive practices and field realties.
Engineering is not only a maze of differential equations, tensors, matrix algebra, or developing software program. It is much beyond these, where all these mathematical techniques are mere tools in the hands of a capable engineer who can intuitively visualize the behavior of the structure and foundation he is going to design and check his
intuitive deduction based on the above tools in hands and this makes it essential to synthesize theory and practice that becomes the hallmark of a complete engineer

Well-designed hybrid structures can combine the different performance strengths materials. This guide focuses on design approaches for concrete structures reinforced in an unconventional way by steel profiles. It explains force transfer mechanisms of steel profiles and oncrete interfaces, and an analysis of the characteristics of hybrid structures, including slendercomponents. Several types of hybrid designs are addressed: walls and columns with several embedded steel profiles, connections strengthened by steel profiles between steel and composite or reinforced concrete components, including the specific case of shear keys connecting deep beams or flat slabs to columns. The transition zones in partly reinforced concrete and partly composite columns are also covered.
Design of Hybrid Structures draws on the European SMARTCOCO research project of experimentation and numerical modelling, giving practical guidance for designers and introducing the subject for researchers and graduate students.
