DESIGN OF A 12-STORY “THE TRUSS RESIDENCES” HIGH-RISE RESIDENTIAL BUILDING IN CUPERTINO, CALIFORNIA, USA

Abstract

The project presents design and planning for the 12 story reinforced concrete residential tower, The Truss Residences, at 10101 N Wolfe Road, Cupertino, California. It contains a one story basement along with the ground commercial level and 11 floors of 110 apartment units. The main objectives of the project were to design a structurally safe residential building, with an appropriate foundation and a stormwater drainage system, all of which would meet building code requirements, safety requirements and be economically feasible. As a result of the work, the most economical gravity load-resisting system selected for design was a two-way slab combined with minor beams. The designed frames incorporated seismic and wind load resistance capabilities along with torsional effect computations during calculations. Iterations to the load distribution were needed during the sizing process according to ACI 318-19 standards for all members including slabs and beams and columns. Stability assessment using SAP2000 software models followed to verify stability alongside hand calculations of internal forces and lateral drifts. The soil response analysis of geotechnical design led to Class C soil identification which affected foundation design standards. Group pile foundations were preferred over single piles and shallow foundations because their performance and capacity for bearing load surpassed both options. The chosen softwares PLAXIS and GEO5 confirmed that foundation bearing capacity and settlement met all safety requirements. For environmental engineering, drainage systems were designed which included pipes within a network built for environmental purposes. A software-based elevation chart development enabled us to determine the topography and create appropriate pipe installations and flow paths. The process of cost-benefit evaluation took place within construction management. Analysis confirmed how durable materials produce extended cost savings.
