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 ... -
Seismic response of torsionally coupled structure with elasto-plastic base isolation
(1994)An analysis of a one-storey model of a torsionally coupled base isolated building for two-component random ground motion is presented. The base isolator consists of an array of elastomeric bearings between the base of the ... -
Review of flexible risers and articulated storage systems
(1994)The anchorage system for mid-ocean loading or production consists of an articulated tower for mooring the tanker. Flexible risers are also essential components of the anchorage system. The present paper provides a ... -
Two-stage solution for framed tube buildings
(1994)A two-stage solution procedure is presented for the lateral load analysis of framed tubes. In the first stage dual shape functions and Gauss elimination solution are used to obtain an approximate solution. In the second ... -
Maximum required bisectorial reinforcement force in embankments on soft ground
(1994)In the rotational stability analysis of reinforced embankments on soft ground, the maximum required reinforcement force to achieve the desired target factor of safety is usually determined by a total stress analysis, using ... -
Vibration of continuous bridges under moving vehicles
(1994)The dynamic behaviour of multi-span continuous bridges under a moving vehicular load is investigated by considering the effect of interaction between the vehicle and the bridge pavement, the torsion in the bridge due to ... -
Lateral-torsional motion of tall buildings to along-wind forces
(1994)The study is concerned with the three-dimensional response of tall buildings (rectangular in plan) to along-wind dynamic forces. For the response analysis, a method based on a spectral approach with matrix formulation is ... -
Geotextile French drains in Indian rural roads — A case study
(1993)This paper presents a case study of the application of geotextile French drains to unsurfaced Indian rural roads. These roads are usually in a deplorable state owing to the accumulation of rainwater and household sewage ... -
Lithological discrimination of sun-facing and shadowed portions of Aravalli region
(1993)Surface illumination in the mountainous terrains is characterized differently on the sun-facing and shadowed portions of the geologic units. This causes misclassification of the litho-units using satellite remotely sensed ... -
Rotational stability of narrow-crested reinforced embankments on soft soils
(1993)The design of reinforced embankments on soft soils is usually governed by their rotational stability. For wide-crested embankments, the authors recently developed simple solutions which can be used to determine the critical ... -
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 ... -
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 ... -
Geotechnical behavior of fly ash mixed with randomly oriented fiber inclusions
(2003)Fly ash is a waste produced from burning of coal in thermal power stations. The staggering increase in the production of fly ash and its disposal in an environmentally friendly manner is increasingly becoming a matter of ... -
Fuzzy set approach in mass transit mode choice
(1993)In Calcutta metro, railways, roads and waterways are available to provide mass transport services. An attempt has been made to use non-conventional abstract mathematical theory to solve the multimodal mass transport system. ... -
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 ... -

A review of deterministic, stochastic and hybrid vehicular exhaust emission models
(2004)Vehicles spend more time near junctions and intersections in different driving modes, i.e., queuing, decelerating or accelerating and thus generating more pollutants than at road links [Claggett, M., Shrock, J., Noll, K.E., ... -
