Abstract Building fires are sometimes unavoidable due to unexpected accidents. During the fire, structural elements exposed temperatures above 1000 °C. Structural concrete loses its strength and stiffness during heating cooling cycle. In most cases, a real cooled by water quenching. It is rare scenario that, buildings subjected fire natural air without forced spraying. However, concrete’s resid...

Based on Zhonghua Road Bridge in Liaocheng city, a single tower hybrid cable-stayed bridge, the stress of steelconcrete joint girder is studied using finite element method with software MIDAS and ANSYS. The beam model whole bridge established CIVIL, from which internal forces critical sections steel–concrete under six adverse conditions are obtained. Then, results applied refined solid-shell Wi...

As a result of increasingly rigorous environmental legislation and industry adoption waste minimization recommendations, the development recycling reuse possibilities for metal-related trash has become important.Inthis research, calcium oxide mixture calcium, iron, magnesium oxides was extracted from wastes cement factories using hydrofluoric acid. result, this research provides comprehensive p...

We investigate the X-ray properties of PG 1004+130, a radio-loud broad absorption line (BAL) quasar with a hybrid FR I/FR II radio morphology. This optically bright, low-redshift quasar was undetected by Einstein, marking it as anomalously X-ray weak relative to other radio-loud quasars. The 22.2 ks XMM-Newton and 41.6 ks Chandra observations presented here are the first X-ray detections of PG ...
