The uncertainties of earthquake currently were not considered with the various lateral load patterns of pushover. The convex set theory, which requires much less information, is employed to model the uncertainties of the seismic influence coefficient maximum and the characteristic period of response spectrum. Then the convex analysis method is integrated into the fundamental equation of pushover, and the analytic relationship of lateral seismic load and top displacement of buildings is derived. The results of numerical example shows that the new lateral load pattern of pushover proposed in this research may effective simulate the uncertainties of strong ground motion.

Earthquake Load

A research about structural analysis of eight-story office building due to earthquake load and to identify the performance level of the structure referring to ATC-40. Performance Based Seismic Evaluation (PBSE) concept is used for earthquake engineering by using one of the method which is Pushover Analysis to evaluate the structure. This method is to purposely apply escalating static lateral load to the structure until failure occurs to the structural elements and targeted structural displacement was obtained. Determining the targeted displacement is referring to ATC-40, FEMA 365, and FEMA 440. Results show that targeted displacement value is 0,015 m for X direction and Y direction as well as the total drift was obtained as much as 0,0066 m for X direction and 0,00273 m for Y direction. According to the structural deformation and criteria from ATC-40 the performance level of the structure is at Immediately Occupancy (IO).

Diagrid structures are evolved as one of the best structural system for high rise buildings. In this study seismic performance of 36 stories Tube-in-Tube Diagrid Structure with various diagonal slopes is evaluated by Non Linear Static Analysis. Tube-in-Tube diagrid structures are modified Diagrid structures in which gravity core is replaced with Diagrid core. Single tube diagrid structure is also studied for comparison. The structure is pushed gradually proportional to fundamental Mode shape. The analysis results shows that Tube-in-Tube structure possess higher stiffness and Lateral Load resisting capacity. The pushover analysis demonstrates that diagrid core can perform better by hardening the structure. According to analysis results, the Tube-in-Tube diagrid structure shows higher non-linear lateral displacement. It was observed that as the diagrid angle increases the stiffness and lateral load carrying strength decreases.
