Campus Lab report Site: Underground car park & South lawn
Site: Lot 6 CafÊ Lot 6 CafÊ is an expressive building, main materials of its frame structure are concrete and steel. Viewing from outside, the concrete columns and beams framing is fairly rigid, most joints are concealed. The concrete structural elements are likely to be pre-fabricated due to the fact that the concrete surface is smooth. Shown in below picture the building’s glass enclosure system. A major interior steel frame transfers the load to concrete columns also it distributes load to a brick column in front of the building.
Underground car park is constructed with concrete reinforced shells (embedded with steel) supported by concrete columns which are placed evenly throughout the basement level. The upper part of columns integrate with the roof. Each column is set in a concrete pad footing separated from path so that the loads are transferred straight down to the ground. Construction joints on the column are expressed joints as there are clear grooves on the column. As shown in above picture, efflorescence appears on concrete suggesting that concrete has absorbed moisture from soil.
Site: Union House Stairs
Site: Frank Tate Pavilion
Three types of steel member can be seen in the stairs structure, namely PFC (Parallel flange channel), I-beam and steel cable. Steel elements are galvanized to prevent the outdoors stairs from rusting. As an express structure the stairs’ framing is fully exposed. In the cable and I-beam structure, I-beam is the major element that bearing the compression. Cable is not in great tension yet it prevent the stairs from swaying therefore it stabilizes the part.
drainage
Main materials of Frank Tate Pavilion are timber and steel. Timber panels cover most part of steel skeleton, however on the edges steel beams coated with zinc are exposed. The pavilion appears to be sculptural with its unevenly supported canopy. The pavilion body integrated with concrete mass which counterpoise the structure. The pavilion is well functioned promoting users an informal learning environment and shelter.

Soldier course PFC

The structural steel skeleton is mostly concealed in timber canopy. Yet steel elements such as beams and joints can still be seen. Due to the unique shape of the canopy, the gravity centre is not in the geometric centre of the structure, As shown in the picture on the left, to maintain stability, such structure should be supported at the opposite corner of its heavy part.
Building behind pavilion. An expressive concrete building with concrete beams and columns framing. The surface has timber texture for aesthetic purpose.
Learning:
Glossary: Foundation: is the lowest division of a buildingits substructure-constructed partly or wholly below the sureface of the ground. (Ching,2008, p. 3.02). Masonry: refers to buildings with units of various nature or manufactured products. Usually with the use of mortar as a bounding agent. (Ching, 2008, p. 2.06). Settlement: the gradual subsiding of a structure as the soil beneath its foundation consolidates under loadings. (Ching,2008, p. 3.02). Structural elements: the design of a structural element is based on the loads to be carried, the material used and the form and shape chosen for the elements. The elements or building terms, specific names which are used for convenience. (Envs, 2014).
