~This report presents the first stage of an investigation of the response to random noise of a stiffened cylinder, representing an aircraft fuselage, including an analysis of the lower modes of such a cylinder. Preliminary investigations suggested that assumptions and approximations which are valid for the uniform, i.e., unstiffened, shell are not necessarily valid for a shell with heavy stiffe...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...

during the last few decades, steel shear walls have been adopted as efficient lateral resisting systems for high rise structures and numerous researches have been conducted on their static and dynamic behavior. steel shear walls have been utilized for retrofitting existing structures, as well as in design of new buildings in japan and usa. in this research, we have focused on the optimization o...

Of the several cases of accidents, fall a vehicle from ship during loading and unloading occurred due to break in clevis ramp door. This study focused on construction door LCT Lady Primus 39.5 m. The purpose this is determine voltage characteristics that occur construction, location most critical components safety factor value under each condition. research uses finite element method (FEM) refe...

Abstract This paper presents a robust assessment of debond in glass fibre-reinforced polymer composite structure with L-stiffener attachment. Towards this, the ultrasonic guided wave (GW) propagation based laboratory experiments have been carried out on stiffened panel piezoelectric transducers for excitation GWs and scanning laser Doppler vibrometer sensing GW propagation. To study changes cau...

Vertical load was applied uniformly over the entire top surface of the plate, and the load was increased in increments. For each load increment, the equilibrium state of the problem was determined. Because of the continuously hardening postyield behavior of Titanium Grade 7, equilibrium could be achieved for any vertical load. However, at a certain load level, the region of the plate between th...
