Strength Calculation Model for Standoff Screws in Composite Joists
… standoff screws. An improved strength prediction model is developed that considers all applicable limit states and determines maximum strength of a connector. A reliability study was also conducted to derive strength reduction factors to be used in design. Parameters considered in the model …

Life cycle cost analysis of asphalt and concrete pavements
… The purpose of this project is to develop a calculation model based on LCCA methodology. LCCA is tested for six traffic groups: 2.500, 5.000, 7.500, 10.000, 12.500, and 15.000 veh/day/lane. For each traffic group, two scenarios are built: one with asphalt pavement and one with concrete …
