Peninsular Malaysia is most affected by the distant Sumatra subduction zone earthquake. Meanwhile, Eastern was subjected to major Philippine and Indonesian Most of offshore platform at Terengganu, Sabah, Sarawak. More than 65% structure exceed range design between 20-30 years. This research aims determine vulnerability risk analysis for existing 3-legged under earthquake load, study behaviors a...

Viscoelastic dampers are considered to be better than most of the passive energy dissipation devices. Researches done on the improvement of its performance for analyzing structures has always been in vogue. The significant change in the response of the structures to make it resistant to earthquake and wind forces is the main idea behind using such devices. A comparative analysis of a G+44 RCC s...

Until recently, computational power was insufficient to diagonalize atmospheric datasets of order 10 10 elements. Eigenanalysis of tens of thousands of variables now can achieve massive data compression for spatial fields with strong correlation properties. Application of eigenanalysis to 26,394 variable dimensions, for three severe weather datasets (tornado, hail and wind) retains 9 11 princip...

The most important property of a base-isolation system is to make the base more flexible than the elements of the superstructure, but it must still be stiff enough to resist typical pounding forces, wind loadings, and similar low-amplitude horizontal forces. However, the potential consequences of earthquake-induced poundings on seismically isolated buildings can be much more substantial, and, t...

The purpose of this study is to assess the sensitivity of four highway bridges to wind and live loadings. The bridges are plarmed for construction on U.S. 59 in Houston, Texas. Each bridge will be of the tied-arch type and will be constructed on-grade over cut areas with clear spans in excess of 61 :reters (200 feet). To expedite construction, unique procedures are plarmed Which use existing br...

To control structures against wind and earthquake excitations, Adaptive Neuro Fuzzy Inference Systems and Neural Networks are combined in this study. The control scheme consists of an ANFIS inverse model of the structure to assess the control force. Considering existing ANFIS controllers, which require a second controller to generate training data, the authors’ approach does not need anot...

the number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. in the past, earth dams usually designed with pure clay core, but in recent decades t...

Dynamic behavior of soil are evaluated relative to a number of factors including: strain level, density, number of cycles, material type, fine content, geosynthetic inclusion, saturation, and effective stress .This paper investigate the dynamic behavior of saturated reinforced sand under cyclic stress condition. The cyclic triaxial tests are conducted on remolded specimens under various CSR whi...
