This book gathers the latest advances, innovations, and applications in the field of effective methods of calculation, resource-saving technologies, and advanced materials in civil and environmental engineering, as presented by leading international researchers and engineers at the XVIII International Scientific Conference Current Issues of Civil and Environmental Engineering Lviv- Koice Rzeszów, held in Rzeszów, Poland, on September 68, 2023. It covers highly diverse topics, including structural shaping and optimization; aspects of structural behavior and modeling; advanced analysis methods; experimental tests and numerical simulations; design codes, in particular Eurocodes and other national and regional limit state codes; and highway and bridges engineering. It also discusses modern architectural and structural solutions; innovative materials and products; durability and maintenance; fabrication and erection; sustainability in construction; renewable energy sources; heat, gas, and water supply; ventilation and air-conditioning; ecological and energy-saving technologies, modern water purification, and treatment technologies; and the protection of water ecosystems. This book, which was selected by means of a rigorous international peer-review process, highlights numerous exciting ideas that will spur novel research directions and foster multidisciplinary collaborations.

Presents the state of the art of civil engineering in Eastern Europe Includes a thematic session devoted to resource-saving technologies and advanced construction materials Written by leading experts in the field
