Experimental Study on Effectiveness of MTMD in Reducing Structural Response of Multi-story Asymmetric model Under Harmonic Loading.
Abstract: The current trend toward construction of high rise building with the use of lightweight, high strength material and advance construction methods have led to making comparatively light and flexible structures, which have relatively low natural damping. Results make structures more prone to environmental excitation such as earthquake loads. An asymmetry in a building which may arise due to unsymmetrical distribution of stiffness, mass, damping and strength characteristics. The responses of …

Experimental Study on Effectiveness of TMD in Reducing Torsional Motion under Harmonic Base Motion
Abstract: AbstractAsymmetry in the building could arise due to unsymmetrical distribution of mass, stiffness, damping and/or strength characteristics. The earthquake response of asymmetric buildings is characterized by coupling between translational and rotational degrees of freedom (dofs). This paper includes an experimental analysis of one storied asymmetrical building frame subjected to harmonic motion with and without tuned mass damper (TMD). Experimentation is done on a shake table and readings were recorded. The …

POLYMER AND COMPOSITE-BASED GEOSYNTHETIC REINFORCEMENTS FOR SEISMIC STABILITY OF SOIL RETAINING STRUCTURES: MATERIALS, MECHANICS, AND PERFORMANCE REVIEW
Abstract: Geosynthetic materials based on polymer and composites have become important items for the structural performance and seismic resilience of the reinforced soil retaining systems. Mechanically stabilized earth walls in recent geotechnical engineering practice are increasingly based on enhanced polymeric reinforcements for enhanced tensile strength, durability, flexibility, and energy dissipation under dynamic loading. High-density polyethylene, polypropylene, polyester, and fiber-reinforced polymer composites are usually used. The present review focus on the recent …

Dynamic Behavior of Coal Ash
Abstract: Coal ash is deposited in large quantities in the ash pond. It is used as structural fill and for dyke construction. The behavior of ash under dynamic conditions is not well investigated. The present work attempts to quantify some of the parameters, which influences the dynamic stability especially liquefaction potential of coal ash. Several investigations conducted on coal ash suggest that ash fills have low SPT value. This supports the …

Experimental Investigation of Effect of Soil Structure Interaction on Buildings
Abstract: In the conventional analysis and design, buildings are generally considered to be fixed at their bases, but in actual practice, the support condition depends on the type of soil on which it is founded. The flexibility of the soil medium allows the movement of soil and foundation, which decreases in the overall stiffness of building frames and results in a subsequent increase in natural periods of the system. Thus, the …

Geohydrological Investigation of a Lake: Case Study of Lake of Sayf Thulfiqar
Abstract: AbstractA reservoir is defined as an enlarged natural or artificial lake. A reservoir, also, means storage pond or using dam to store water. An artificial lake namely "Sayf Thulfiqar" is decided to be constructed artificially in the region of Bahar Al-Najaf in Najaf province in Iraq for storage and aesthetic purposes. The soil of the region is unsaturated above water table and it is mainly sand as classified according to …
