Stress State and Several Problems of Estimating the Actual Operation of Effective Bridge Superstructelements during the actual operation of effective bridge superstructures with orthotropic deck plates. A brief description of the design solution of orthotropic deck plates is presented. It is stated that, from a structural point of view, significant saving of steel in the case of orthotropic deck p

Durability and Assessment of Early Post-tensioned Bridgesive environment, environmental conditions, and inadequate maintenance lead to the poor condition of early post-tensioned bridges. Tendons and anchorages are failing by corrosion and with excessive traffic load, some bridges are close to partial or total collapse. Inspection of several early post-ten

Impact of Duration and Intensity of Seismic Records on the Soil-Steel Bridge Behavior structure. It is well known that in seismic analysis the duration and intensity are very important, not just the ground acceleration caused by the seismic excitation. In addition, these aspects have a significant impact on the load capacity of the structure, so their response under seismic excitati

Impact of Reinforcement Layer in Soil-Steel Culvert on Laboratory and Numerical Tests their simplicity of construction and low construction costs in relation to traditional bridge structures made of concrete, steel, or wood. Despite the high popularity of these objects, knowledge about their behavior under various load is relatively limited. An even bigger problem can be noticed whe

Rheological Properties of Concrete Based on Waste Materials the factory producing products from red ceramics. In total, five mixtures were tested. One without and four with the addition of fibers. Steel cord from recycled car tires and steel fibers in the amount of 0.5% and 1.0% by volume of fiber-concrete was used. The research was conducted for a period o

Effect of the Addition of Waste Fibers on Some Properties of Concrete waste fibers are produced during recycling process of the end-of-life car tires. Those fibers are called steel cord. Standard concrete with different amounts of waste fibers was tested. The applied amounts of fiber reinforcement were accordingly 0.5%, 0.75%, 1.0%, 1.25%, and 1.5%. In the tests, com
