Analysis of cable-stayed bridges under multi-component random ground motion by response spectrum method
(2000)A response spectrum method is presented for the seismic analysis of cable-stayed bridges subjected to partially correlated stationary random ground motion. The method is based on the relationship between the power spectral ... -
Anisotropic strength and deformational behavior of Himalayan schists
(2002)Anisotropy, which is characteristic of metamorphic rocks such as schists, is due to a process of metamorphic differentiation. Preferred orientation of minerals like mica and chlorite in response to tectonic stresses makes ... -
Application of extreme value theory for predicting violations of air quality standards for an urban road intersection
(1999)Extreme value theory (EVT) has been used for making predictions of the expected number of violations of the National Ambient Air Quality Standards (NAAQS) as prescribed by the Central Pollution Control Board (CPCB), India, ... -
Application of intervention analysis for assessing the effectiveness of CO pollution control legislation in India
(1999)An Intervention Analysis Model (IAM) (Box and Tiao, 1975) was developed to study the impact of the intervention brought in by the Government of India (GoI), to control the CO pollution caused by the vehicular exhaust ... -
Artificial neural network approach for modelling nitrogen dioxide dispersion from vehicular exhaust emissions
(2004)Artificial neural networks (ANNs) are useful alternative techniques in modelling the complex vehicular exhaust emission (VEE) dispersion phenomena. This paper describes a step-by-step procedure to model the nitrogen dioxide ... -
Assessment of permeation quality of concrete through mercury intrusion porosimetry
(2004)Permeation quality of laboratory cast concrete beams was determined through initial surface absorption test (ISAT). The pore system characteristics of the same concrete beam specimens were determined through mercury intrusion ... -
Behaviour of equipment mounted over a torsionally coupled structure with sliding support
(2000)Behaviour of a light equipment system mounted over a torsionally coupled and sliding primary system, is studied under bidirectional ground excitation. A fictitious spring model is considered in the analysis to deal with ... -
A class of inhomogeneous shear models for seismic analysis of landfills
(1998)An analytical/numerical procedure is developed to calculate the shear elasto-plastic earthquake response of hill-shaped landfills. Landfill response is evaluated on the basis of newly developed one-dimensional inhomogeneous ... -
Compressive strength of cement stabilized fly ash-soil mixtures
(1999)Rajghat fly ash from Delhi, India, and Baumineral fly ash near Bochum, Germany, were mixed with the locally available soils—silt and Yamuna sand with Rajghat fly ash and Rhine sand with Baumineral fly ash—in different ... -
Control of suspension bridge flutter instability using pole-placement technique
(2005)The closed-loop state feedback control scheme by pole-placement technique, which is widely used in control literature, is applied to control the flutter instability of suspension bridges. When the mean wind speed U at the ... -
Development of decision support system for resolution of construction disputes: a systemic approach
(2001)This paper sets forth a framework for understanding and administratively resolving disputes over time delay and extension in Indian construction contracts by means of a decision support system. This decision support system ... -
Directional Dependency of Reinforcement Force in Reinforced Embankments on Soft Soil
(1996)in the limit equilibrium method of rotational stability analysis of reinforced embankments on sof't soils, the maximum required reinforced force is determined assuming that the eitforced acts in a particular direction ... -
Dynamic analysis of arch bridges under travelling loads
(1995)A dynamic analysis of arch bridges traversed by a single moving load is presented using a mixed approach in which the advantages of continuum and lumped mass methods have been combined. The bridge deck is idealized by a ... -
Dynamic behavior of offshore spar platforms under regular sea waves
(2003)Many innovative floating offshore structures have been proposed for cost effectiveness of oil and gas exploration and production in water depths exceeding one thousand meters in recent years. One such type of platform is ... -
Dynamic behaviour of square and triangular offshore tension leg platforms under regular wave loads
(2002)Among compliant platforms, the tension leg platform (TLP) is a hybrid structure. With respect to the horizontal degrees of freedom, it is compliant and behaves like to a floating structure, whereas with respect to the ... -
Dynamic response of trussed bridges for moving loads
(1993)A continuum approach is presented to obtain the transverse vibration of trussed bridges traversed by a single moving load. The efficiency and the accuracy of the method are determined by comparing its results with those ... -
The effect of berms and tension cracks on the maximum reinforcement force in embankments on soft soils
(1994)The rotational stability of reinforced embankments on soft soils is usually investigated by a total stress analysis using a limit equilibrium approach, assuming a circular slip surface. Solutions are presented in the paper ... -
Empirical methods to estimate the strength of jointed rock masses
(2005)The ultimate strength and deformation of jointed rock mass are important parameters that designers look for in selecting sites for foundations of civil and mining engineering structures in rocks. In the field, it is extremely ... -
Engineering geological and geotechnical responses of schistose rocks from dam project areas in India
(1996)For a rational and safer design of civil and mining engineering structures in or on rocks, a proper understanding of the quality of rock mass is required. To assess the rock mass quality, evaluation of physical and mechanical ... -
Final and binding power clauses in Indian construction contracts
(2001)Most Indian construction contracts while specifying the role and responsibilities of parties in the contracts, also specify certain extraordinary powers to a particular person whose decisions are final and binding to both ...
