Abstract: In Post-tensioned concrete beams, the longitudinal compressive stress from concentrated to linearly distributed produces high transverse tensile stresses in the vertical direction. When this tensile stresses exceed the modulus of rupture of the concrete, the anchorage zone has cracks. The appropriate vertical reinforcement is required based on calculation of tensile stresses (bursting stresses). In this study, the analytical results were used to examine the validity of different proposals for bursting force. The angle of tendons, eccentricity, and shape of anchorage were considered as variables. This comparison demonstrates that the Morsch equation is able to predict bursting force reasonably well than the other equations.

Abstract: Road fatalities in India have increased to 150,785 in year 2016. Karnataka, a major Indian state, appeared at 4th rank with 11,133 road fatalities. Karnataka lost 17.8 persons per 100,000 population against India average of 11.9 persons. Karnataka is committed to road safety, therefore, in order to reduce road injuries by multi-sectoral interventions, an existing two lane undivided road section- Belgaum to Yaragatti (62 km)- was selected as a pilot project based on recommendations of iRAP (International Road Assessment Programme) under Safe Corridor Demonstration Programme (SCDP) funded by World Bank. Road crash data of the corridor were collected of past five years for analysis and proposed engineering designs were reviewed. Engineering interventions modified eight major junctions with medians, right turning lanes, 31 minor junctions with improved road signs and markings, construction of walkways with guard rails near most junctions, bus-bays and shelters, traffic calming, overall roa
