<p>The aim of this Study is to identify the most common types of cracks and defects which occur in Izki road and suggest suitable option for maintenance. The objectives are to identify different types of cracks &amp; defects, to find out the different ...

<p>The formation of cracks in structural elements and other parts of a building such as walls is often unavoidable; that is why some standard of practice specify the maximum allowable width of cracks depending on the type and exposure conditions of a structure. ...

<p>In this paper, a numerical code, RFPA2D (rock failure process analysis), was used to simulate the initiation and propagation of fractures around a pre existing single cavity and multiple cavities in brittle rocks. Both static and dynamic loads were applied ...

<p>To quantify the support provided by the shotcrete, flexural strength tests were conducted with two common, commercially available fiber-reinforced shotcrete (FRS) mixes using the round determinant panel (RDP) test method, ASTM C 1550. A portable RDP test ...

Researchers at National Institute for Occupational Safety and Health (NIOSH) are investigating how fiber-reinforced shotcrete mix designs can be extrapolated from proven designs employing wire mesh. This paper explains the results of round determinate panel ...

In this paper is reported results of changes in elastic moduli measured during increasing amplitude cyclic stressing experiments on dry and water-saturated samples of Etna basalt.

Over the past decades, an increasing number of integral bridges have been built. This is justified by the various advantages of integral bridges in comparison with standard bridges equipped with expansion joints and bearings. In particular, integral bridges ...

It is the purpose of this paper to show how RCC design and construction techniques were developed with time and how RCC is today applied in a general way at South African dams.

<p>The crack in concrete dam body is considered as a typical damage to concrete gravity dams during large earthquakes, and lots of researches on a nonlinear dynamic analysis method considering the occurrence and progress of cracks have been carried out in ...

This thesis contains details of an investigation into the applicability of Griffith's brittle fracture theory, modified to account for the effects of crack closure in compression, to the prediction of rock fracture behaviour.
