Abstract:
Buildings in Chile are mostly structured with reinforced concrete walls. This structural system has been used for the construction of residential buildings since 1930. The use of structural walls in such buildings provides adequate strength and stiffness. These characteristics have led to adequate seismic performance of structural wall buildings following the 1985 and 2010 earthquake in Chile. The seismic design of such buildings is conducted using the NCh433 and NCh430 codes. The NCh433 specifies the design spectra, the strength reduction factor and the intersory drift limits, where the use of structural wall buildings is promoted. The NCh430 is the concrete design code, which adopts ACI 318 with some modifications. This presentation will summarize the relevant aspects of the seismic design provisions for reinforced concrete wall buildings in Chile.
