Reliability Based Design Optimization of Gravity Retaining Walls

Probabilistic Applications in Geotechnical Engineering, 2007
In this paper the use of probability theory in reliability based optimum design of reinforced gravity retaining wall is described. The formulation for computing system reliability index is presented. A parametric study is conducted using advanced first order second moment method (AFOSM) developed by Hasofer-Lind and Rackwitz-Fiessler (HL-RF) to asses ...

External Stability Analysis of Narrow Backfilled Gravity Retaining Walls

Geotechnical and Geological Engineering, 2020
A three wedge failure mechanism is proposed to determine active earth pressure exerted by narrow backfills on gravity retaining walls and its point of application. Gravity retaining wall proportions are optimized against external failure modes using proposed active earth pressure and its line of action of resultant thrust.

Reliability Based Pseudo-Dynamic Analysis of Gravity Retaining Walls

Indian Geotechnical Journal, 2017
Pseudo-dynamic method of analysis, considering the effect of earthquake loading, shear and primary waves, results in more realistic values of earth pressures than the commonly used pseudo-static method. To account for the uncertainties of geotechnical parameters, conventionally, either a global Factor of Safety (FS) to the entire structure or a ...

Foundation design for gravity retaining walls under earthquake

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2018
Economical design of gravity retaining wall systems subject to earthquake can be achieved by recognising that, although modest earthquake acceleration may bring the wall system to limiting equilibrium, the criterion for satisfactory performance is the residual displacement of the wall after the earthquake.

Insight into the seismic response of gravity retaining walls

Géotechnique
An extensive study of gravity walls subjected to strong seismic excitation is presented, exploring the role of parameters such as the width of wall, the type of excitation (idealised wavelets or recorded accelerograms), the peak ground acceleration (PGA), the dominant period (TP) of the wavelets, the accelerogram’s polarity and the coefficient of ...

OPTIMUM DESIGN OF THE SYMMETRICAL GRAVITY RETAINING WALLS

2018
Retaining walls are one of the important applications in civil engineering. When the height of the wall is not too high, the gravity retaining walls, which are one of the retaining wall types, are widely used. Since the shear and bending moments in the wall sections are carried by the wall material in the gravity retaining walls, there is no need for ...
