Local residents were evacuated from their homes in response to reports of a "massive leak" and strong scent of natural gas. As the construction industry is striding towards the industrialization of green buildings, a precast concrete frame beam-column joint with high-strength reinforcement was proposed. Learn more. Concrete is strong and ductile in compression, it is weak and brittle in tension, and hence its response to external loads is improved by pre-compression. The second day of the meet is called 'Hair of the Dog' and is a more family orientated race day. [115] In this configuration the bridge remained in use until 1977, but extensive repair work was carried out in the early 1930s. If heavy clay soil is present it is good practice to increase the void depth to as much as 225mm or possibly more. A single-span truss bridge is like a simply supported beam because it carries vertical loads by bending.

These include: two important works of public art by Norman Carlberg, the internationally acclaimed American sculptor who worked in the modular constructivist style and studied under Josef Albers at Yale in the late 1950s. These loads are transferred both to the towers, which carry them by vertical compression to the ground, and to the anchorages, which must resist the inward and sometimes vertical pull of the cables. Geological Series Sheet 8527 (Edition 1)1990, Australia1:100 000, Tumut Mineralogical Map.

They are typically used in situations such as sloping sites, areas where the ground has poor bearing capacity, or there is a likelihood of ground volume change. The break through in prestressed concrete applications enables reduced section sizes and reduction in self-weight.
