Abstract The earthquake is the most devastating and unexpected natural phenomenon, causing massive damage to both human lives infrastructure. In this study, two different irregulars Reinforced Cement Concrete (RCC) building plans of 25 th story buildings with ground floor (G+25) 9 storey (G+9) were subjected four zones making a total eight model structures test their ability withstand gravity s...

This paper presents measurement and analysis of the dynamic response of a five-story building to very-high frequency excitation (> 100 Hz) from blasting vibrations originating from a contiguous excavation of rock. Velocity response measurements, in the rock and on the structure, were employed to calculate time correlated dynamic displacement response of the building to blasting. Time correlated...

In this article I propose a reading of La oscura vida radiante, the last novel by Manuel Rojas, that considers and combines historical series (Chile transitioning from its first to second modernity) with biographical (Aniceto Hevia / Rojas youth maturity). foreground, reader encounters young who, together his fellow anarchists, drifts around without losing integrity lucidity, while at same time...

The response spectra defined in the appropriate Euro standards from first and second generation (EN 1998–1 EN 1998-1-1), which determine seismic load for common buildings, are critically presented first. To avoid a reduction earthquake loading on structures using spectra, only few points of 1998-1-1 determined by applying probabilistic concept hazard assessment. comparison current is made with ...

This study deals with performance-based design optimization (PBDO) of steel moment frames employing four different metaheuristics consisting of genetic algorithm (GA), ant colony optimization (ACO), harmony search (HS), and particle swarm optimization (PSO). In order to evaluate the seismic capacity of the structures, nonlinear pushover analysis is conducted (PBDO). This method is an iterative ...

The MIRAS instrument has a unique reference clock that is distributed to the Control and Monitoring units (CMN) located in the SMOS arms and in the hub. Each CMN uses the clock signal, provided by the Local Oscillator, to generate a reference tone and provide it to a group of six receivers. Although every CMN should generate exactly the same tone, the phase of the tones drifts due to the temper...

With the conceptual development of performance-based design, the earthquake engineering community has begun to recognize the importance of controlling both interstory drifts and absolute floor accelerations. However, these often present conflicting requirements for design. In this paper, we present a multi-objective genetic algorithm to address this conflict by identifying a Pareto front of opt...
