Available in PDF, EPUB and Kindle. Book excerpt: The rolling and sliding motions of a rigid body subject to gravity and supported by a plane surface are treated in elementary texts on dynamics. Rocking of a riding body supported by a horizontal surface which experiences oscillatory accelerations due to an earthquake has been discussed by Housner. If the body is deformable there is a potential for the dynamics of the body deformations to couple with the rocking mode; in particular, resonances in the deformation response can develop sufficient reaction moment at the base to cause base uplift which would not occur if the body were rigid. The paper presents a model suitable for studying this phenomena including the magnitude of the uplift, impacts occurring during stable rocking motions, and overturning. The equations governing the plane motion of a deformable body with rocking boundary conditions supported by a horizontal flat surface subject to vertical and horizontal accelerations are derived. These equations depend on dynamic parameters of the body which are defined in terms of integrals of assumed modes of deformation. The number of assumed modes is arbitrary. Motions which involve uplift but not overturning are termed rocking motions and are characterized by impacts with the supporting plane. Integration of these equations requires care in dealing with high frequency rocking motions may occur.

Available in PDF, EPUB and Kindle. Book excerpt: The rocking response of rigid bodies with rectangular footprint, freely standing on a horizontal rigid plane is studied analytically. Rigid bodies are subjected to simulated single component of horizontal earthquake time histories. The effect of the baseline correction, applied to simulated excitations, on the rocking response is first examined. The sensitiveness of rocking motion to the details of simulated earthquakes and the geometric properties of rigid bodies (i.e., slenderness ratio and sizeparameter) as well as the coefficient of restitution is investigated. Because of the demonstrated sensitivity of rocking response of rigid bodies to these factors, prediction of rocking stability must be made in the framework of probability theory. Therefore, using a large number of simulated earthquakes, the effects of duration and shape of intensity function of simulated earthquakes on the overturning probability of rigid bodies are next studied. In the case when a rigid body is placed on any floor of a building, the corresponding overturning probability is compared to that of a body placed on theground. For this purpose, several shear frames with fundamental natural period of vibration ranging from 0.5 sec(stiff) to 2.0 sec (flexible) are employed. Finally, the viability of the energy balance equation which was introduced by Housner in 1963 (The behavior of inverted pendulum structures during earthquakes, Bulletin of Seismological Society of America, 53, 2, 403-417) and widely used by the nuclear power industry to estimate the rocking stability of rigid bodies is evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains eight contributions on the common theme of masonry construction. The publication coincides with the retirement of Dr Jacques Heyman from his Professorship of Engineering in the University of Cambridge, and Headship of the University's Engineering Department. It is entirely appropriate to have a collection of papers in honour of Professor Heyman at this time; for he has made signal contributions to our understanding of masonry construction over the past thirty years or so. It is no exaggeration to say that he has radically changed the way in which engineers think about masonry structures, particularly in relation to the old ecclesiastical buildings and bridges. Indeed it is hard to imagine what this subject would be like today in the absence of Professor Heyman's seminal papers.

Available in PDF, EPUB and Kindle. Book excerpt: Thank you for opening the second edition of this monograph, which is devoted to the study of a class of nonsmooth dynamical systems of the general form: ::i; = g(x,u) (0. 1) f(x, t) 2: 0 where x E JRn is the system's state vector, u E JRm is the vector of inputs, and the function f (-, . ) represents a unilateral constraint that is imposed on the state. More precisely, we shall restrict ourselves to a subclass of such systems, namely mechanical systems subject to unilateral constraints on the position, whose dynamical equations may be in a first instance written as: ii= g(q,q,u) (0. 2) f(q, t) 2: 0 where q E JRn is the vector of generalized coordinates of the system and u is an in put (or controller) that generally involves a state feedback loop, i. e. u= u(q, q, t, z), with z= Z(z, q, q, t) when the controller is a dynamic state feedback. Mechanical systems composed of rigid bodies interacting fall into this subclass. A general prop erty of systems as in (0. 1) and (0. 2) is that their solutions are nonsmooth (with respect to time): Nonsmoothness arises primarily from the occurence of impacts (or collisions, or percussions) in the dynamical behaviour, when the trajectories attain the surface f(x, t) = O. They are necessary to keep the trajectories within the subspace = {x : f(x, t) 2: O} of the system's state space.
Download or read book Rocking and Overturning Response of Rigid Bodies to Earthquake Motions written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental study of the rocking and overturning response of massive concrete blocks (with relatively high aspect ratio) to simultaneous horizontal and vertical earthquake ground motions is presented. This problem occurs when large concrete blocks are used as radiation shields in particle accelerators or similar nuclear installations. The results of this study also offer insight into the response of the rigid bodies (such as are approximated by some electrical machinery and mechanical equipment) which are not anchored to the ground. The mathematical model used was based on the assumption of a constant coefficient of restitution. A computer program was written to predict the rocking and overturning behavior of rigid rectangular blocks under simultaneously applied horizontal and vertical ground accelerations. Using the computer program, the response of rigid blocks of various aspect ratios and sizes was studied under the accelerograms of various strong motion earthquakes.
