Abstract In earlier days, the only way to resist lateral loads was increase strength of structure obtained by making larger cross sections and massive buildings. Structural control is one solutions important topics in both points view security comfort recent years. To reduce effect seismic energy, structural forms used outrigger. years, supplementary devices are installed into outrigger so that...

As the demand and construction of cable-stayed bridges have increased, research on safety in event natural disasters such as fires explosions is actively being conducted. If a bridge damaged by an unexpected disaster or accident, it can cause serious traffic congestion huge economic losses. This study evaluates usability cable damage. Additionally, seismic performance impact damage are evaluate...

In this work the robustness properties of Integral Sliding Mode Controller (ISMC) are studied for problem structural vibration. Selecting sliding manifold which takes into account attenuation unmatched perturbation is as well. This study has two scenarios first comparing types mode controllers designed to control 3-story scaled structure supported by Magneto Rheological Damper (MRD). ISMC compa...

The Regional Earthquake Likelihood Models (RELM) test of earthquake forecasts in California was the first competitive evaluation of forecasts of future earthquake occurrence. Participants submitted expected probabilities of occurrence of M ≥ 4.95 earthquakes in 0.1° × 0.1° cells for the period 1 January 1, 2006, to December 31, 2010. Probabilities were submitted for 7,682 cells in California an...

retrofitting structures is an important issue. structural weakness may be due to changes in design codes or defects in implementation. adding structural floors to the existing structures may also lead to the need for strengthening and retrofitting. retrofitting is possible before the earthquake or may take place as rehabilitation of damaged members after earthquake. elements such as columns in ...
