The proposed thesis will include an investigation of an alternate lateral resisting system as staggered steel truss system. The existing structure contains extraordinary number of load bearing masonry shear wall in a non-seismic zone, which raises a question about the efficiency and necessity of all shear walls the structure has. With the repetitive floor layout of residential hotel building, staggered truss was chosen to take the advantage of layout and minimize the design conflicts. To compare the existing lateral system and the alternate system, the existing load bearing masonry shear walls and moment frames will be examined, steel staggered truss system will be investigated and designed.
During this redesign process, other breadths require careful considerations. The floor plan layout of lower floor of hotel which uses steel moment frames for lobby spaces may need readjustment with staggered truss system implementation. As an architectural breadth study, redesign of floor layout of lower levels and change in façade design will be investigated. With the change in lateral resisting system material, difference in cost of alternate system and scheduling of different sequencing method need to be investigated as well. Therefore, cost analysis and scheduling will be studied and compared to the existing structure as construction management breadth topic.
