As the frequency of earthquakes has increased in Korea recent years, designing earthquake-resistant facilities been increasingly emphasized. Structures constructed with rebars are vulnerable to shaking, which reduces their seismic performance and may result damage human life property. Because construction requires maintenance sub-constructions, such as by cutting or compensating for missing reb...

In this paper, we describe how, through the combination of field testing and finite element simulation, bonding anchoring performance small-diameter rebar under action medium low cycle fatigue load was studied corresponding conclusions were obtained: ① Through test, parameters 6 mm 8 planting specimens obtained after subjected to 10,000, 50,000 100,000 times loading at depths 10d, 15d 20d. The ...

a 3-year-old arabian colt was presented for a major gingiva wound at the right rostral part of mandible. after clinical assessments, rostral mandibular fracture was determined. stabilization of fractured region was achieved via cerclage wire application under general anesthesia. fixation wires were left in place for 6 weeks. a 3 -month follow up revealed complete fracture healing. the purpose o...

absractall perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. the most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. the reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

Abstract The bond–slip model plays an important role in the structural analysis of reinforced concrete structures. However, many factors affect behavior, which means that a large number tests are required to establish accurate model. This paper aims data-driven method for prediction historical with few test specimens and features. Therefore, new Mahalanobis-Meta-learning Net algorithm was propo...

To meet the requirements of specifications, intelligent optimization steel bar blanking can improve resource utilization and promote development sustainable construction. As one most important building materials in construction engineering, reinforcing bars (rebar) account for more than 30% cost civil engineering. A significant amount cutting waste is generated during phase. Excessive increases...

Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...
