41. CFD and data-driven modeling for safe spillway discharge
Sammanfattning : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. LÄS MER
42. Dynamic Behaviour of Concrete Structures subjected to Blast and Fragment Impacts
Sammanfattning : For protective structures, reinforced concrete is commonly used. Concrete structures subjected to explosive loading in a combination of blast and fragments will have very different response than statically loaded structure. LÄS MER
43. Strengthening of concrete structures by the use of mineral based composites : system and design models for flexure and shear
Sammanfattning : A great number of society's resources are invested in existing concrete structures, such as bridges, tunnels, different kind of buildings etc. All of these structures have both an expected function and an expected life span. However, both the function and the life span can be influenced by external factors, e.g. LÄS MER
44. Structural Analysis Methods for the Assessment of Reinforced Concrete Slabs
Sammanfattning : Reinforced concrete (RC) slabs are among the most critical parts of the load-carrying capacity of such structures as bridges and parking decks. Previous research indicated that the assessment methods used in current practices largely underestimated the load-carrying capacity. LÄS MER
45. An Algorithmic Framework for Intelligent Concrete Structural Defects Detection and Classification
Sammanfattning : The primary objective of inspecting concrete civil structures is to gather information concerning the deterioration of concrete elements, including issues like concrete cover cracking, delamination, or corrosion. Typically, this data is documented through field inspection notes, hand-drawn sketches, and photographs. LÄS MER
