Classification of Weathering in Rocks and Its Engineering Implications- Juniper Publishers

Image
Juniper Publishers- Journal of Civil Engineering Abstract A critical review on the description and classification of weathering in rocks has been presented in this paper. This paper starts with a brief description on several factors causing weathering in rocks followed by the weathering mechanism and the description of weathering in rocks. A review of existing codes and guidelines on weathering and its implications to describe the engineering properties of rocks has been presented. From the point of view that weathering process modify the mass engineering properties of rocks which are quite unpredictable, this type of review work becomes necessary. The present paper forms a useful source of information for geologists and geotechnical engineers working on weathered rocks. Keywords: Rock; Weathering; Classification; Guidelines; Engineering properties Introduction Weathering of rocks is a purely subjective term and i...

Geoid Modelling for Surveying Works Using Satellite Geo-Spatial Data- Juniper Publishers

Image
 Civil Engineering Research Journal- Juniper Publishers   Introduction Nowadays fully three-dimensional positions - latitude, longitude and height are commonly provided by Global Positioning Systems (GPS) with WGS84 ellipsoid as a reference surface. The knowledge of terrain heights is very essential for several surveying and civil engineering works. The type of heights needed for such applications is a height above mean sea level (MSL), usually called orthometric height. A precise geoid model is required to transform GPS-based geodetic heights to orthometric height to allow such data to be directly used in surveying and civil engineering applications [1]. The process of geoid modelling can only be performed if dense networks of precise levelling or gravity and astronomical deflections of vertical are made available. Go to Objective The objective of this article is to formulate a local geoid model that would allow utilization of GNSS data in the fields of surveying and civil en...

Designing Steel Bridges against Fire Hazard- Juniper Publishers

Image
Juniper Publishers- Journal of Civil Engineering Abstract Bridge fires can lead to significant economic and public losses; however, no provisions are specified for fire resistance of bridge structural members in current codes and standards. This paper presents an approach for mitigating fire hazard in steel bridges. The approach comprises of two steps, estimating fire risk in a bridge, and then developing strategies for enhancing fire resistance of a critical bridge. An analytical procedure is employed to derive a fire-based importance factor to estimate the vulnerability of a bridge to fire, and then a sequential finite element analysis is carried out to develop strategies for mitigating fire hazard in that bridge. The validity and applicability of this approach is demonstrated through a case study on a steel bridge that experienced fire recently. Keywords: Fire hazard; Bridges; Fire; Mitigation strategies; Finite element analysis ...
