VARIATION OF THE WALL CLAY ACTING UPON THE SEISMIC PERFORMANCE OF A MUD WALL

Abstract

In this paper, we discuss the variation effect of the wall clay strength to the seismic performance of a mud wall. The material tests of wall clay are a compression test and a split test. Five specimens are tested in each test. The variation coefficients of wall clay are over a range of 0.04-0.13. The lateral loading test for mud wall shows that the seismic performances of mud clay have small dispersion against the result of their material tests. This phenomenon is confirmed by the numerical analysis considered the dispersion of material strength. The numerical analysis also represents that the average of material strength is sufficient to calculate the seismic performance of a mud wall.
