Triangular-based communication towers result in significant weight reduction compared to conventional square-based towers. Hot-rolled 90° steel equal angle sections with bent-up gusset plates are used for triangular towers, since 60° angles are not readily available in India. In triangular towers, the included angle between two flanges of the main leg member shall be 60° for smooth connection between leg and bracing members. The required included angle of 60° between the two flanges of a leg mem...

Toward developing greener cement, the use of supplementary cementitious materials (SCMs) are inevitable in cement. Fly ash is the more abundantly available SCM which is pozzolanic in nature and helps largely in the development of long-term strength. When such type of SCMs are incorporated in cement, considering 90-day compressive strength is more appropriate instead of 28 days. However, in this fast-growing world, it is not feasible to wait for 90 days to obtain the complete gain in strength of ...

This paper presents a genetic algorithm and nonlinear programming (GA–NLP) hybrid model to derive steady state optimal reservoir operating policies for a multi-purpose reservoir. In the present study, the objective is maximizing the net benefits from all the crops in the command area considering yield response to water deficit and the hydro-power generation subject to constraints on reservoir water balance, storage bounds, channel capacities and minimum water requirements. Decision variables of ...

Cage wheel is commonly used with walking tractors, but its diameter suitable for getting maximum tractive performance needs to be studied. Hence, an open-lug-type variable-diameter cage wheel to fit with a walking tractor was designed using SOLIDWORKS 2016 software. After verifying its dimensions by using finite element analysis, an actual wheel was fabricated with provision to vary its diameter from 620 to 710 mm using a manually operated hydraulic jack. Its performance in terms of tractive eff...

Heavy metals are frequently encountered in domestic wastewaters (sources being the usage of paints, batteries, electronic goods, etc.). It can get carried away by storm water through municipal sewer systems to the domestic wastewater treatment plants and affecting the biomass. The present work aims to study the impact of nickel [Ni(II)] ion on settling characteristics, metabolic activity and morphology of aerobic sludge biomass in sequential batch reactors (SBRs) in addition to reactor performan...

Globally traffic scenario has experienced a vast change over the years as volumes of traffic on urban roads have increased by leaps and bounds. This increase has also marked an increase in the number of road accidents, both fatal and non-fatal. Accident prediction has a significant role in the improvement in traffic safety, and urban traffic management. Different statistical methods and various soft computing techniques are being used for developing accident prediction models. In this study, ens...

Cement is one of the most widely used materials in construction. This study presents a process-wise evaluation of energy use and CO2 emissions for clinker, Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC) using the principles of life-cycle assessment. Two cement plants located in India are considered as typical case studies. The gate-to-gate system boundary condition is considered. The energy use for clinker is found to be 3990 and 3626 MJ/ton for case studies 1 and 2, respecti...

Several statistical methods, viz. flood frequency analysis and hydro-meteorological methods (i.e., unit hydrograph approach) are available for estimation of design flood in un-gauged catchments. Till today, the empirical formulae are relevant as the latest methods require adequate field observation and collection of sufficient data. The available formulae such as Dicken’s formula, Ryves formula and Inglis formula are applicable, respectively, to Northern India, Western India and Southern India. ...

The unexpected local damage may happen in the beam column connections of steel structures under lateral loads, since the connection is the focal point. Adopting reduced beam section (RBS) is an innovative method to dissipate the energy of such structures since it will enable a plastic hinge to be formed in the beam portion, thus reducing large stress concentration in the connection. Also, the formation of plastic hinge will satisfy the seismic criteria of strong column and weak beam combination....

Yield line analysis of reinforced concrete slab, simply supported on two sides perpendicular to the span and free on the other two sides, carrying concentrated load at different locations is carried out by determining the critical failure mechanism and the corresponding equilibrium equation analytically. Such slabs are often encountered in the form of culverts with concentrated vehicular loads. In practice, elastic methods of analysis are used for their analysis. However, the use of yield line a...
