Summary

Truss bridges are the oldest bridge designs that are being used around the world for the transportation of goods as well as people across rivers, lakes and difficult terrains. They have helped human a lot by allowing them to move with access load from place to place easily. …

Introduction to Engineering - Truss Bridge Design

This model successfully worked to hold desired load and effectively fulfilled the load resistance qualities that a practical bridge must have. Keywords Truss bridge, bridge competition, bridge model, bridge stability. Introduction Bridge design is the fundamental part of civil engineering and most critical as well. It is designed for transportation of heavy traffic; meanwhile, it is constructed to cope with environmental effects like storms. There are many types of bridges that are being used around the world, among them most common are arch bridges, girder bridges, truss bridges, cantilever bridges, cable stayed bridges, moveable bridges and suspension bridges(SWE, 2012). The type of bridge that we incorporated in our design is the truss bridge. These are the oldest and the most economical bridges found around the world with excellent weight bearing capacity(BuildingBig, 2010). Atypical truss bridge is shown below: Specialty of truss bridges is the triangular elements present in the structure to share the load applied on the bridge by the traffic(JHU). In a typical truss bridge design the horizontal members are responsible for bearing loads as a result of horizontal as well as dynamic compression.
In our bridge design we made use of Popsicle sticks to create truss members as well as the base of the bridge. These sticks were joined together by making use of glue. ...

This is achieved by providing solutions for both consumer and commercial applications. Civil engineering is one of the oldest fields in engineering that arose out of the many challenges that humanity experienced in the early days. Civil engineers are concerned with overseeing the construction of tunnels, roads, bridges, airports and many other infrastructures. In the course of their job, civil engineers take account of several factors just to ensure that the final product meets the standards expected. This is done taking account of the fact that the products are normally expected to last for…

This paper documents the early stages of a research project which aims to segment the Standard Drive Cycle definitions into a series of operating characteristic windows which can then be searched for and automatically extracted from general driving behaviour of a car on the road, and thereafter concatenated to re-creating a real-world equivalent of the Standard Drive Cycle without the need for rolling road or laboratory testing. 1 Introduction Fuel economy has risen to prominence in recent years and most automobile markets require adherence to local fuel economy standards. It has been realised…

As a result of this governments in various parts of the world have come up with creative ways of reversing this predicament. 1. Introduction Zero carbon urban design is a revolutionary move that has been favoured by many governments in the past few years with the aim of curbing the damage caused by adverse climate changes. From a documentary by Al Gore (2006), the major causes of greenhouse effect are the by-products of industrialization, and especially carbon dioxide. The level of Carbon dioxide, the main constituent of emission by vehicles, is linked to consumption of fuel by the vehicle.…

Creative problem solving is a core component in finding solutions to the vast wastes by human growth and development that are compatible with the environment. Half of the current world population lives in urban centres and the rapid urbanisation has been a major challenge to scientists on how to maintain this population’s health without affecting the environment (Morrison & Rauch 2007). In a forum for research on the management and the effect that transportation has on the environment, some of the issues addressed included the traffic management, treatment, sustainable transport strategies,…
