The current practice of considering tha dynamic behaviour
of retaining walls is to take into account an increase in the lateral
earth pressure as calculated from the modified Coulomb formula. This
has serious limitations.

Critical evaluatic.n of the ?xisting literature on dynamic and earthquake forces on pile foundations embedded in .soils, reveals the need for further studies on this subject
This thesis presents the theoretical and ...
Well foundations of bridges are subjected to vertical
forces due to dead load of structure, live load of vehicles,
buoyancy pressures and vertical inertial forces due to earth
quakes. They are subjected to horizontal ...
Cable-stayed bridges are structural systems in
which inclined cables emanate from one or more points of
supporting towers and hold large span stiffening girders
of the bridge deck at intermediate locations between ...
Studies of seismic performance of brick build
ings have revealed their inadequacy to resist earth
quake shocks due to their heavy weight, poor tensile
strength, low shearing resistance, lack of proper
bonding between ...
This investigation deals with the dynamic behaviour
of axisymmetric structures with emphasis on the effects due to
strong ground motion. A linear elastic analysis in time
domain using timewise mode superposition method ...
Analysis has first been developed for evaluating the
sliding and rocking responses of rigid objects resting on
plane surfaces under combined horizontal and vertical compo
nents of earthquake motion and then extended to ...
Ductility signifies the ability of a structure or a member
to undergo inelastic deflections beyond the point of first yield
under static/dynamic loading while maintaining a certain maximum
load carrying capacity. It is ...
Microearthquake investigations involve collection and study of data for small
magnitude events (MO). The rate of occurrence of small magnitude events being high
as compared to that of moderate and big ones, their recording ...
The frequent occurrence of destructive earthquakes
in the past in various places such as, Santa Barbara,
USA (1906); Koyna, India (1967); San Fernando, USA (1971);
Chile (1985) and other places, causing loss of thousands ...
Monitoring of earthquakes provides basic data for seismological
investigations and research. The advancement of digital technology has
made it possible to record the seismic signals from many seismometer
stations ...
Strong ground motion data is the primary input for earthquake response analysis
and design of structures, equipments and other life line systems. The best description
of strong earthquakes is provided by accelerographs ...
Earthquake protection by base isolation of buildings has attracted
considerable attention in recent years. The main concept here is to
isolate the structures from ground instead of the conventional
techniques of ...
A feasible technical solution of the seismic isolation system for
multi-storey brick masonry buildings is presented in the Thesis
Solution is based on the previous achievements in the area of base
isolation technology, ...
This thesis presents a comprehensive material model which is capable
of simulating the in-plane behaviour of masonry from elastic range to
final failure for any angle of bed joint orientation. The final element
model ...
This thesis aims to study the salient features of large-sized ferrocement tanks
subjected to static and dynamic loads and to investigate their suitability and economy
over r.c. tanks. These tanks featuring undulated wall ...
Plain land in hills is scare and therefore sloping land is being increasingly used for
buildings. Economic development of hilly areas, have a marked effect on the buildings in
terms of style, material and method of ...
With increasing load, a structure undergoes increasing deformation. Beyond a critical
or peak load level, structure's inability to take any more loads causes failure. Failure can be
distributed or localized. In general, ...
In recent years analysis of axisymmetric structures, such as hyperbolic cooling
towers, chimneys, reactor containment shells, etc., subjected to dynamic or
seismic loading has attracted considerable attention, specially ...
The dynamic stiffness properties of soils must be determined for the purpose of
analyzing machine foundations and substructures subjected to earthquakes. The
significant advances in mathematical techniques for analyzing ...
