In recent years, rocking isolation has become an effective approach to improve seismic performance of steel and reinforced concrete structures. These systems can mitigate structural damage through rigid body displacement and thus relatively low requirements for structural ductility, which can significantly improve seismic resilience of structures and reduce repairing costs after strong earthquakes. A number of base rocking structural systems with only a single rocking interface have been proposed. However, these systems can have significant high mode effect for high rise structures due to the single rocking interface. This RObust BUilding SysTem (ROBUST) project is a collaborative China-New Zealand project sponsored by the International Joint Research Laboratory of Earthquake Engineering (ILEE), Tongji University, and a number of agencies and universities within New Zealand including the BRANZ, Comflor, Earthquake Commission, HERA, QuakeCoRE, QuakeCentre, University of Auckland, and the University of Canterbury. A number of structural configurations will be tested [1, 2], and non-structural elements including ceilings, infilling walls, glazed curtain walls, precast concrete panels, piping system will also be tested in this project [3]. Within this study, a multiple rocking column steel structural system was proposed and investigated mainly by Tongji team with assistance of NZ members. The concept of rocking column system initiates from the structure of Chinese ancient wooden pagoda. In some of Chinese wooden pagodas, there are continuous core columns hanged only at the top of each pagoda, which is not connected to each stories. This core column can effectively avoid collapse of the whole structure under large storey drifts. Likewise, there are also central continuous columns in the newly proposed steel rocking column system, which can avoid weak story failure mechanism and make story drifts more uniform. In the proposed rocking column system, the structure can switch between an elastic rigidly connected moment resisting frame and a controlled rocking column system when subjected to strong ground motion excitations. The main seismic energy can be dissipated by asymmetric friction beam–column connections, thereby effectively reducing residual displacement of the structure under seismic loading without causing excessive damage to structural members. Re–centering of the structure is provided not only by gravity load carried by rocking columns, but also by mould coil springs. To investigate dynamic properties of the proposed system under different levels of ground excitations, a full-scale threestory steel rocking column structural system with central continuous columns is to be tested using the International joint research Laboratory of Earthquake Engineering (ILEE) facilities, Shanghai, China and an analytical model is established. A finite element model is also developed using ABAQUS to simulate the structural dynamic responses. The rocking column system proposed in this paper is shown to produce resilient design with quick repair or replacement.

A photograph of two people from BECA at the Winter Survival Kit launch at Shirley Intermediate School. In the background are the 'All Righties' and Ciaran Fox from All Right?. All Right? posted the photograph on their Facebook Timeline on 25 July 2014 at 4:02pm. The Facebook image is captioned, "All paid for by the wonderful people at BECA... who collected money from their staff around the world after the February earthquake. Good people.

An image encouraging people to take notice. The image depicts an 'All Rightie' in a fluorescent vest standing by a road cone and gazing at the night sky and reads, "When was your last moment of wonder? Sometimes the quietest moments can really change our perspective." The image was from phase 2 of the All Right? campaign, promoting the Five Ways to Wellbeing. The Five Ways to Wellbeing is a simple, evidence-based approach to improving wellbeing, promoted by the Mental Heath Foundation.

A PDF copy of four Adshel poster designs, each depicting a different way that people can improve their wellbeing. Three out of four designs depict different images and wellbeing tips from earlier posters promoting the Five Ways to Wellbeing. The slogans read, "What good things are you growing?", "Shown a mate you care lately?", "When was your last moment of wonder?" and "When did you last share your hidden talents?" The posters were from a later stage of phase 2 of the All Right? campaign, promoting the Five Ways to Wellbeing. The Five Ways to Wellbeing is a simple, evidence-based approach to improving wellbeing, promoted by the Mental Health Foundation.
