Craking of reinforced concrete beams

Informes de la Construccion, 1969
Se pasa revista a diversas teorías existentes sobre fisuración, justificando al paso las fórmulas contenidas en la nueva Instrucción de Hormigón E. H. 68, recientemente aprobada en España con carácter interministerial. Se ofrecen diversas fórmulas y ábacos de comprobación y se exponen los trabajos más recientes del Comité Europeo del Hormigón sobre la ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

Sustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its

Seismic strengthening of beam-column joints with multidirectional CFRP laminates

, 2012
An experimental program was carried out to analyse the potentialities of a technique based on the use of multidirectional CFRP laminates (MDL-CFRP) for the seismic repair and strengthening of reinforced concrete (RC) beam-column joints. This experimental

The Role of Global Political Economy in Community‐Based Adaptation to Climate Change—Practitioners' Experience and Opinions

Sustainable Development, EarlyView.
ABSTRACT Community‐based adaptation scholars and practitioners acknowledge that power asymmetries pose significant barriers to project impact. Nevertheless, there is little research on the role of the global political economy as the root cause of vulnerability.
