This paper is in two sections. The senior author discusses in the first section the reasons for some of the revised provisions in the current Ministry of Works, Structural Design Office, Code of Practice for the design of buildings, while the junior author deals in the second part with the application of these provisions to a reinforced concrete shear core building. He presents methods of designing and detailing a core for ductility and the effect of incremental damage to the spandrels in a coupled shear wall are examined.

The recently published New Zealand Code of Practice for the Design of Concrete Structures (NZS 3101:1982) and the newly amended Code of Practice for General Structural Design and Design Loadings for Buildings (NZS 4203) permit a variety of possible design approaches for reinforced concrete shear wall structures. A series of wall designs for dimensionally similar four-storey and eight-storey buildings has been carried out and a comparison of construction cost estimates obtained together with an assessment of the relative design effort required for the different design options.

Current State

As high-rise buildings increase with height and slenderness, they become increasingly sensitive to dynamic vibrations, and therefore the natural frequency of vibration and damping ratio are very important design parameters, as they directly impact the design wind forces. Recent advances in sensing and computing technology have made it possible to monitor the dynamic behaviour of full-scale structures, which was not possible in the past. Full-scale validation of the dynamic properties is useful for high-rise designers to verify design assumptions, especially since recent measurements have shown that damping decreases as the height of the building increases, and in situ damping measurements have been lower than many currently assumed design values, potentially leading to unconservative designs. A 50-storey residential building in downtown Toronto, with a reinforced concrete coupled shear wall lateral load resisting system with outriggers was monitored using current state-of-the-art sensing technologies and techniques to determine, in situ, the dynamic properties under real wind loads. The in situ measurements were then compared with results obtained using current state-of-the-art computer modelling techniques.

Coupled Shear Wall

Coupling beams are essential structural elements of reinforced concrete coupled shear wall to resist earthquakes and other lateral loads. But many current reinforced concrete coupling beams are insufficient in resisting lateral loads due to their bad ductility. So a test of retrofitting methods of deep coupling beams with steel plates since their good performance in the ductility and deformation was made to find ways of improving the ductility of the beams, and the results of this retrofitting method prove good because of the incensement of the ductility, deformation and strength of the beams.

Abstract The current paper studies the effect of superior eigen-modes on the seismic response for a series of reinforced concrete structures having eigen-periods near code control periods. Although the structural design is based on Romanian seismic design codes (“P100-1/2013 - Seismic design code - Part 1 - Design provisions for buildings” and “SR-EN 1998/2004 - Design of structures for earthquake resistance”), it carries some importance for other countries with similar seismic design spectra. A total of twenty-four models for structures were considered by varying their location (through control period values), three-dimensional regularity, overall dimensions and height regime. Results were compared and conclusions were drawn based on percentage values of relative displacements (storey drifts) and base shear forces.

Shear Demand

A displacement based method for the seismic design of reinforced concrete shear wall buildings of regular shape is presented. For preliminary design, approximate estimates of the yield and ultimate displacements are obtained, the former from simple empirical relations, and the latter to keep the ductility demand within ductility capacity and to limit the maximum storey drift to that specified by the codes. For a multi-storey building, the structure is converted to an equivalent single-degree-of-freedom system using an assumed deformation shape that is representative of the first mode. The required base shear strength of the system is determined from the inelastic demand spectrum corresponding to the ductility demand. In subsequent iterations a pushover analysis for the force distribution based on the first mode is used to obtain better estimates of yield and ultimate displacements taking into account stability under P–Δ effect. A multi-mode pushover analysis is carried out to find more accurate estimates of the shear demand.

Difficulties in applying the seismic design provisions of the
NZ Standard Code of Practice for General Structural Design and Design Loadings for Buildings, NZS 4203:1976, to multi-component petrochemical facilities lead to the preparation of the document: Seismic Design of Petrochemical Plants - Volume 1: Recommendations and Volume 2: Commentary. This paper explains the basis of that document. The philosophy
that is used provides for a consistent level of earthquake protection
to the various components of a petrochemical facility according to the importance of the component and the potential hazard associated with its failure. This is achieved by establishing design load levels based on assessed seismic risk and structure reliability. An important part of the philosophy is the minimising of seismic risk by the elimination or modification of potentially hazardous situations at the conceptual design stage. The derivation of basic seismic design coefficients from a
seismicity study of New Zealand is described and the analysis and
detailing procedures adopted in the Recommendations for structures and equipment in petrochemical facilities are discussed. Particular attention is given to explaining the application of capacity design principles to ductile structural forms.
