program, but the organizing committee encourages the participation of any team and to that end, will assist any team’s search for financial support to attend the competition. 1.2 Summary of Rule Changes 1.2.a Just as in the 2006 competition hosted by PEER and EERI, a performance based scoring method will be used, and is based on three primary components: annual income, annual initial building cost, and annual seismic cost. These three components will be used to calculate the structural performance, in terms of annual revenue. The team with the largest annual revenue will be the winning team. Details of each component are given in Sections 5 and 6. 1.2.b Detailed restrictions placed on damping devices are included section 2.9.i. 1.2.c PEER will not ship the base and roof plates to each team before the competition. Rather, upon arrival, each team will receive their base and roof plates, at which time they may attach them to the structure. Further details are included in sections 2.10 and 2.11. 1.2.d The annual income generated by rentable floor space has been reduced by roughly 30% and noted in section 5.1. 1.2.e Sponsor names and logos are permitted on the structure in accordance with section 2.3. 1.3 Structural Design Objective Your team has been hired to submit a design for a multi-level commercial office building. To verify the seismic load resistance system, a scaled model must be constructed from balsa wood and will be tested under severe earthquake simulation. Model structures shall be constructed at a scale of 72:1. Structures will be tested on the UCIST unidirectional earthquake shake table, with plan dimensions of 45.7 cm by 45.7 cm (18.0 inch by 18.0 inch) and a payload capacity of 15.0 kg (33 lb). Structures should withstand scaled versions of ground motions recorded during the 1940 El Centro, 1994 Northridge and 1995 Kobe earthquakes, which will be available online at the following website: http://peer.berkeley.edu/students/Seismic.html Seismic performance of the designated structure will be evaluated by monitoring the accelerations at the roof and on the shake table. Accelerations will be integrated, as discussed in Section 3.0, to obtain displacements. A structure that has a low peak drift ratio between the roof and the shake table is desired, as well as a low peak roof acceleration. Model dimension details are as specified: Maximum number of floor levels: 29 levels Minimum number of floor levels: 15 levels Maximum building plan dimensions: 39.4 cm (15.5 inch) square Undergraduate Seismic Design Competition 3
Minimum individual floor plan area: 232 cm 2 (36.0 inch 2 ) Total building floor plan area (all floors): 1 m 2 to 3 m 2 (10.76 ft 2 to 32.3 ft 2 ) Required floor height: 5.08 cm (2.00 inch), See section 6.4 for tolerances Required lobby level height (1 st level): 10.2 cm (4.00 inch), See section 6.4 for tolerances Maximum Model height: 1.52 m (5 ft) Diaphragms (floors): Actual floors need not be constructed, beam members are adequate 1.4 Tentative Competition Schedule The competition schedule presented below is subject to change.
