the flow of forces (Structure Craft, 2013). These engineered timber members range from 2.6m at the piers and 0.9m at the centre of the span (Structure Craft, 2013). In addition to the engineered timber, tensioned rods tie the cantilevered glulam to concrete abutments at either end of the bridge (Structure Craft, 2013). c. Load Paths The image below displays the varying load paths of the Bow River Pedestrian Bridge. The red arrows represent the permanent (dead) load which…

2.4 Positive impacts of sand mining and gravel extraction worldwide Sand and gravel had been a useful natural resource for thousands of years worldwide and are fundamental to human existence. Today, demand for sand and gravel has increased. Mining operators in conjunction with resource agencies need to work hard and make sure the extraction is done responsibly. Schaetzl (1990) discussed sand and gravel as crucial resources to economic development activities when making aggregate in United…

One of the first accounts of Brutalism was given by architectural critic Reyner Banham in his seminal essay titled New Brutalism published in the Architectural Review in 1955, Banham’s conception of New Brutalism was both a movement in the sense of futurism and a style. Banham’s etymology of the term New Brutalism is clarified through his complex and contradictory explanation of Brutalism as both a movement and style. Banham did articulate clearly three underlying rules which are its core…

4.1 First Side by Side Geometry The first model shown in figure 3 was for twin tunnels already constructed at a centre to centre spacing of 3D. This model helped to identify the influence of construction sequence on surface and subsurface ground displacement upon excavating the first and second tunnels underneath the existing twin tunnels. Figure 3: First Side by Side twin tunnels 4.1.1 Surface Displacements The surface displacements at distances of 4.75m, 7.125m, 9.5m and 11.875m from the…

The Roman Roads were built by the military, also surveyors and engineers. The rule fell under the consul rule though. They were built with big stones and sand on the bottom. Then in the middle there were rocks and gravel and on the top there was concrete paving stone. Also on the sides of the roads there was a huge drainage system for all the water when it rains. The Roman Roads stretch from the Appian Way and even to the Mediterranean. This stretch…

There are many outstanding achievements that are associated with the Roman civilization. One of the most remarkable of these groundbreaking structures is the aqueducts. The way they were built, and the history of these complex architectural designs contributed to Rome’s prosperity. The everyday life of the Roman people certainly would have been very different if the channels would have failed. The people of Rome used these aqueducts, that were located in mainly rivers with the purpose…

Similar to PC concrete, w/b ratio significantly affects the strength of M-S-H mortar mixtures, demonstrated by the increase of compressive strength at all testing ages as water content decreases. The mortar samples at 28 days age obtained low strength of only 20 MPa with…

Earthen materials show interesting environmental advantages when used to build [1]. These materials are becoming increasingly important in the context of the modern desire of construction materials which are less highly processed and have low toxicity [2][3][4]. Nowadays, there are several available techniques where these materials can be used with structural purposes, namely as earth blocks (adobe), compressed earth blocks (CEB), rammed earth and cob [5] but the lack of scientific data and lack…
