Passive And Semi-Active Structure-Multiple Tuned Liquid Damper Systems, Islam Soliman
Passive And Semi-Active Structure-Multiple Tuned Liquid Damper Systems, Islam Soliman
Electronic Thesis and Dissertation Repository
The resonant vibration motion of tall buildings due to dynamic loading, such as wind storms and earthquakes, can be reduced by adding passive dynamic vibration absorbers (DVAs). A single sway mode of vibration is usually considered, however, for certain structures, multiple modes may need to be suppressed. Furthermore, the location of the TLD on the floor plate is important for certain modes, such as the torsional mode. As a result, a three dimensional finite element structure-TLD system model capable of dynamically analyzing a 3D structure is developed and validated. Two different nonlinear TLD models are considered. A full dynamic analysis …

Comparison Between Three Types Of Cable Stayed Bridges Using Structural Optimization, Olfat Sarhang Zadeh
Electronic Thesis and Dissertation Repository
Cable stayed bridges have good stability, optimum use of structural materials, aesthetic, relatively low design and maintenance costs, and efficient structural characteristics. Therefore, this type of bridges are becoming more and more popular and are usually preferred for long span crossings compared to suspension bridges. A cable-stayed bridge consists of one or more towers with cables supporting the bridge deck. In terms of cable arrangements, the most common type of cable stayed bridges are fan, harp, and semi fan bridges. Because of their large size and nonlinear structural behaviour, the analysis of these types of bridges is more complicated than …
Load-Sharing Of Toe-Nailed, Roof-To-Wall Connections Under Extreme Wind Loads In Wood-Frame Houses, Mohammad Khan
Load-Sharing Of Toe-Nailed, Roof-To-Wall Connections Under Extreme Wind Loads In Wood-Frame Houses, Mohammad Khan
Electronic Thesis and Dissertation Repository
A typical wood frame house roof consists of trusses which are nailed to the top-plates of the wall assembly. These are known as roof-to-wall connections (RTWCs). A load-sharing mechanism is developed between adjacent RTWCs via roof elements such as roof-sheathing, fascia beams, etc., during high wind loads. An experimental setup was developed to observe the load-sharing behavior between seven connections. To mimic the roof bending stiffness in the direction perpendicular to the trusses, two steel beams with representative bending stiffness were connected across the RTWCs in a simple way. Identical ramp and identical fluctuating wind loads were applied to all …
Enhancement Of Local Buckling Behaviour Of Steel Structures Retrofitted Through Bonding Gfrp Plates, Mohammad Al Amin Siddique
Enhancement Of Local Buckling Behaviour Of Steel Structures Retrofitted Through Bonding Gfrp Plates, Mohammad Al Amin Siddique
Electronic Thesis and Dissertation Repository
An effective technique involving the use of glass fiber reinforced polymer (GFRP) plates to enhance the local buckling behaviour of steel plates, beams, and moment resisting frames is presented in this Thesis. The enhancement in buckling capacity is achieved by bonding GFRP plates to the steel sections. These steel/GFRP joints have the advantages of ease of application, low cost, high strength-to-weight ratio, and resistance to corrosion. An interface element that simulates the behaviour of the adhesive bonding the steel and GFRP elements is developed and is implemented into an in-house developed finite element model to represent steel/GFRP joints. The model …
