High-rise buildings subjected to lateral loads such as wind and earthquake loads must be checked not to exceed the limits on the maximum lateral displacement or the maximum inter-story drift ratios. In this paper, a sensing model for deformed shapes of a building structure in motion is presented. The deformed shape sensing model based on a 2D scanner consists of five modules: (1) module for acq...

The effectiveness of Metallic dampers for seismic response reduction of structures is quite well known in the earthquake engineering community. However, little attention has been paid to evaluating the influence of the number and placement of this type of dampers on the dynamic response. Using genetic algorithms as an optimization technique will allow for the simultaneous number and design of a...

The RC-framed building is one of the most common construction techniques for seismic-resistant structures due to its ductile nature. But seismic performance RC structure affected by various factors among which site soil condition vital. sub-soil affects time period eventually impacts earthquake force in structure, thus making variations loadings. Although several studies have been performed and...

Setback irregularities are considered where discontinuity between adjacent stories is excessive. This irregularity caused the probability of high damage at structures subjected to strong earthquake motion. For this purpose, study was conducted by modeling steel special moment frame (SMF) using a finite element calculation program with nonlinear static analysis compared Padang city’s response sp...

In this paper, optimal design of hybrid low damping base isolation and magnetorheological (MR) damper has been studied. Optimal hybrid base isolation system has been designed to minimize the maximum base drift of low damping base isolation system where for solving the optimization problem, genetic algorithm (GA) has been used. In design procedure the maximum acceleration of the structure has ...

In this article, a Python-programmed advanced design paradigm is firstly introduced to topology and size optimization of the X-bracing system nonlinear inelastic space steel frames. For that purpose, an analysis method considering both geometric material nonlinearities utilized as effective finite element (FEA) solver. which, members are modeled by truss elements, while beam column simulated be...

In Japan, excavated soils generated from construction sites in urban areas are being disposed tolandfill as industrial waste. With limited land big cities, the landfill will be more and scarceand overload state next few years. Therefore, effective use of soil is anurgent issue. Liquefied Stabilized Soil (LSS) one methods using withconstruction works, has become popular Japan. Numerous previous ...

This study aims to investigate the impact of soil-structure interaction (SSI) on seismic behavior reinforced concrete buildings. An advanced numerical model for SSI was developed and verified using ABAQUS software. The response a 12-story building four types soil (rock, dense soil, stiff soft soil) examined Normalized Response Spectra based Moroccan paraseismic regulation RPS 2011. global later...
