A SOLUTION FOR QUARRY LIMESTONE DUST RECYCLING
Quarry dust is a product of the extracting process. In quarrying activities, the rock is extracted and transformed into various sizes: as a waste, a fine aggregate generally useless to be disposed of and able to produce environmental pollution is produced. The disposal of this type of waste is a further cost of the extracting process, further it is a risk especially for subsoil reserves of wa-ter that can be easily reached during rainfalls and for the sea when quarries are close to the coast. The productive use of quarry dust with the double aim of disposal and protection of the environment seems a right strategy. The Italian-Maltese extracting industry covers a great segment in the world w…
OUT OF PLANE CAPACITY OF INFILLS AFTER IN PLANE LOADING: A PREDICTION ANALYTICAL MODEL
Earthquakes produce on infills In-Plane (IP) and Out-Of-Plane (OOP) actions. The recent earthquakes have proved that the OOP collapse of infills is a diffused mechanism also in buildings designed to resist to seismic events in agreement to the most modern strategies. This fact makes the question arises about the safety of infills with respect OOP actions. The strong interaction between IP and OOP behaviour of infills traduces in a progressively reduction of the OOP strength. Further, only in few cases codes suggest adequate strategies to face this issue. For what above, in the paper the reduction of OOP strength because of the IP damage is studied by an extended numerical experimental campa…
Proračunski postupak za ocjenu potresne otpornosti konstrukcijskog sustava okvir-ziđe uzimajući u obzir veličinu, vrstu i razmještaj otvora
Konstrukcijski sustavi okvir-ziđe jedni su od najčešćih vrsta građevnih konstrukcija. Iako se ispunsko ziđe u kojem se ne nalaze otvori pri provjeri potresne otpornosti pouzdano predočava tlačnim štapovima, način uzimanja u obzir veličine, vrste i razmještaja otvora u ziđu nije u potpunosti razjašnjen. Nekolicina razvijenih proračunskih postupaka u kojima se razmatra ovaj problem su, ili proračunski vrlo zahtjevni, ili su nepouzdani, jer pokazuju prevelika odstupanja u rezultatima proračuna. Razvijeni proračunski postupak također se temelji postupku zamjenjujućih tlačnih štapova, ali se ziđe u kojem se nalaze otvori raščlanjuje na dovoljan broj dijelova kako bi se izdvojio otvor. Proračunsk…
