The 2012 Emilia earthquakes caused significant damage to existing precast reinforced concrete (RC) industrial buildings not specifically designed resist seismic actions. main failure mechanisms were related the loss of support beams and roof elements by high relative displacements, mechanical connections consequent fall cladding panels, at base columns collapse RC forks top columns. In all case...

This paper presents the development of systematic machine learning (ML) approach to enable explainable and rapid assessment fire resistance fire-induced spalling reinforced concrete (RC) columns. The developed comprises an ensemble three novel ML algorithms namely; random forest (RF), extreme gradient boosted trees (ExGBT), deep (DL). These are trained account for a wide collection geometric ch...

The paper presents an analytical formulation of an element removal algorithm based on dynamic equilibrium and the resulting transient change in system kinematics. The algorithm is implemented into an open-source finite element code, is numerically validated using a benchmark problem with simple element removal criteria, and is able to capture the effect of uncertainty in member capacity. Realis...

The present study investigates how advice writers employ move sequences and modal verbs to achieve intended discourse functions. This paper aims to testify two research hypotheses: 1. Advice writers of different topics employ different moves and modal verbs to achieve discourse function, and 2. The differences may imply writers’ intentions, emotion and expectancy of effects on the readers to in...

Sexual differentiation occurs prenatally in guinea pigs but extends into the postnatal period in rats. Steroids affect the development of two motoneuron nuclei of the rat lumbar spinal cord that innervate sexually dimorphic perineal muscles. The spinal nucleus of the bulbocavernosus (SNB) innervates the bulbocavernosus (BC) and levator ani (LA) muscles while the dorsolateral nucleus (DLN) inner...

Fiber-reinforced polymers (FRPs) have been widely utilized to improve the seismic performance of deficient reinforced concrete (RC) columns. In recent years, one of the emerging types of FRPs used is basalt fibers. In this study, the performance of existing columns was experimentally examined before and after applying near-surface mounted (NSM) basalt FRP (BFRP) rebars as a retrofitting techniq...

This paper presents the application of the harmony search based algorithm to the optimum detailed design of special seismic moment reinforced concrete (RC) frames under earthquake loads based on American Standard specifications. The objective function is selected as the total cost of the frame which includes the cost of concrete, formwork and reinforcing steel for individual members of the fram...

The main aim of the present study is to achieve optimum design of reinforced concrete (RC) plane moment frames using bat algorithm (BA) which is a newly developed meta-heuristic optimization algorithm based on the echolocation behaviour of bats. The objective function is the total cost of the frame and the design constraints are checked during the optimization process based on ACI 318-08 code. ...
