1 SICE XJTLU SEISMIC DESIGN COMPETITION 2014 INTRODUCTION The Student Chapter of ICE (SICE) was established at Xi an Jiaotong-Liverpool University (XJTLU) in September The SICE Design Competition is an annual competition organized by SICE. It aims to encourage creativity and active learning among the students and offers a great opportunity for them to work with the other Student Chapters in Mainland China. The innovation and challenge for this year will be conducted using a specially designed Earthquake Shaking Table. This competition will be held on Saturday, the 26 th of April 2014, in the laboratory of the Department of Civil Engineering, XJTLU, Suzhou, China. MATERIALS Following materials will be provided for this competition: Wooden stick - 5mm diameter and 300mm long (Figure 1). 75 sticks will be provided for each group. Figure 1: Wooden stick 75 Flat wooden stick - 150mm 18mm 2mm (Figure 2). 30 sticks will be provided for each group. Figure 2: Flat wooden stick 30 Page 1 of 5

2 Cotton rope (Figure 3). 1 roll will be provided for each group. Figure 3: Cotton rope 1 Glue gun (Figure 4). 1 gun will be provided for each group. Figure 4: Glue gun 1 Glass board - 300mm 300mm (Figure 5). 1 board will be provided for each group. N.B. Figure 5: Glass board 1 Only the materials listed above can be used in the competition. Any breach to this regulation will lead to a direct disqualification. Page 2 of 5

3 The glass board provided need to be fixed on the shaking table via holding down bolts. It is important not to destroy any bolt holes on the glass board during the construction of your superstructure. DESIGN REQUIREMENTS I. The total height of the structure must be between 0.5m-2.0m. Any structure outside this range will be eliminated from the competition. II. III. The base of the structure should be glued firmly to the glass board provided. The connection between the base and the superstructure is essential. The total height is measured from the top of the glass board to the top floor level which can carry a standard weight of 2kg, as shown in Figure 6. The extended columns above the top floor will not be taken into account. Figure 6: Measurement of total height IV. The clear height (Figure 7) of each storey must be between 15cm-25cm to ensure that a standard weight of 2kg can be put in. If the clear height of any storey is outside of this range, the total height of the structure will be deducted by 10%. Figure 7: Measurement of clearance between floor levels It should be noted that the connection between the weight and the floor is very important. It is up to the participants to work out a solution to prevent the falling of any weights during the test. Failure to do this may destroy the shaking table and this must be avoided. Page 3 of 5

4 V. The cross-section of any vertical member should contain no more than 2 wooden sticks (Figure 8). Figure 8: No more than 2 sticks to make a column VI. The superstructure must be able to hold a 2kg weight on each floor level during the test. The standard 2kg weight, 97mm in diameter and 37mm in thickness, is shown in Figure 9.

5 FAILURE CRITERIA Structural failure (STR) including the snap failure of the major structural elements including beams, columns and bracings. Loss of equilibrium (EQU). Falling of the weight. JUDGMENT CRITERIA Every structure will be judged according to its: Height (in metre) Selfweight of the structure (in kg) Load carrying capacity (in kg): the total weights (2kg) carried by the structure Peak ground acceleration (in g) Maximum acceleration that the structure can resist before any of the failure criteria discussed above is reached. The final mark will be calculated according to the following equation: Final Mark = Height x Peak ground acceleration x Load carrying capacity Self weight Each group may give a short presentation to introduce their group members and designs.
