PREDICTION OF UNCONFINED COMPRESSIVE STRENGTH OF ROCKS BY POINT LOAD STRENGTH INDEX [PDF]
The point load testing is widely used to determine rock strength indeces in geotechnicalpractices as a result to simplicity. The present study presents correlation equations betweenthe unconfined compressive strength (qu) and point load strength index Is(50) adopted fordifferent types of rocks.

Electricity load profile classification using Fuzzy C-Means method [PDF]
This paper presents the Fuzzy C-Means (FCM) clustering method. The FCM technique assigns a degree of membership for each data set to several clusters, thus offering the opportunity to deal with load profiles that could belong to more than one group at ...

A new index combining weak layer and slab properties for snow instability prediction [PDF]
Snow slope stability evaluation requires considering weak layer as well as slab properties – and in particular their interaction. We developed a stability index from snow micro-penetrometer (SMP) measurements and compared it to 129 concurrent point ...

Rock material particle size and its correlation with the point load test index
Abstract: This work proposes the methodology to obtain a correlation between the particle size of the rock material and the point load test index (Is 50), in order to characterize the materials, present in mining projects in terms of resistance. For a correct development of mining activities, both open pit (quarries) and underground (mines), it is ...

Load and resistance factors for prestressed concrete girder bridges
There has been a considerable progress in the reliability-based code development procedures. The load and resistance factors in the AASHTO bridge design code were determined using the statistical parameters from the 1970's and early 1980’s.
