Abstract
Traffic signal poles play a role of mitigating traffic congestions in cities. It slender structure which is usually characteristics with high deformation. It is exposed to load, various environmental factor and natural hazards. The aspiration of modal analysis in structure mechanics is to negotiate the natural frequency of an object or structure in times of free vibration. Conventional poles are replaced with I and T section by applying various material such as structural steel (SS), stainless steel (STS) and grey cast iron (CI). By predicting the ultimate section with low deformation. The ultimate material is endowed and fracture behaviour is prompt, substitute crack is inserted in the maximum stress spot and life cycle of the ultimate material section is deliberate.
Highlights
Traffic signals can lead to a standard distribution of traffic flows [1]
It may have exposed to various load and environmental factor especially wind factor such as hurricane [7],[8]
I and T section offer a high strength long span structural beam. Various material such as structural steel (SS), stainless steel (STS) and cast iron (CI) is applied to the section [1214] to found the minimum deformation by modal analysis [15]
Summary
Traffic signals can lead to a standard distribution of traffic flows [1] It structure is usually characteristic with high deformation [2,3,4,5,6]. It may have exposed to various load and environmental factor especially wind factor such as hurricane [7],[8] It leads to the failure and so the conventional structure is replaced to I and T sections [09-11]. I and T section offer a high strength long span structural beam. Various material such as SS, STS and CI is applied to the section [1214] to found the minimum deformation by modal analysis [15]. In protrusion to the modal analysis, the preferred section is terminated and the fracture behaviour and crack analysis is constituted [26,27,28,29,30] and the life cycle of the component is calculated
