Unreinforced Masonry Building

At 12:51 on 22 February 2011, 12 people died beside me. The parapet and facade of an unreinforced masonry building on the main street of Christchurch, New Zealand, crushed the bus that I was riding. I'm the only one left, the lucky 13th. My leg, my hand, and my soul will never be the same. I broke more bones than the surgeons were willing to count, spent two months in the hospital, and most of a year off work. I walked, slept, and dreamed in a fog for four years. It cost half a million dollars to save my left leg. I treasure that leg, scars and all, but still feel the earthquake in every step. In this opinion paper, I share my story—from the earthquake, to the Bright Light, to the Dark Place, to the hospital, to the Dalai Lama, to the halls of Parliament. I also share the story of a nation coming to grips with its home on the Ring of Fire. The story ends on 8 May 2016, when Parliament passed the new Building Act, complete with a ministerially titled “Brower Amendment” that halved the remediation time for unreinforced masonry parapets and other falling hazards. I conclude with the lessons I've learned on making a difference.

Ground Motion Records

The first case study used in this work is an existing seven-storey unreinforced masonry building (representing a typical residential building located in the district of L ́Example in Barcelona). The accuracy of the non-linear static procedures was evaluated by comparison with non-linear dynamic analyses for seven ground motion records and different levels of seismic intensity. The results obtained from the analyses showed good performance of the static pushover methods on the analysed building. The second case study used in this work is a two-storey unreinforced masonry building which was tested at ELSA in Ispra, Italy. First a modal response spectrum analysis was carried out. Subsequently, non-linear static analysis was performed using two different computer programmes. The results of the present work were compared with experimental results.
