Emergency Regulations and the New Building Code
The 1942 Federal District Building Code was crude and overoptimistic. The 1957 earthquake prompted the drafting of emergency regulations, modern and more realistic. They evolved into the...

Taipei Trade
The appearance of this building is remarkable—so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...

Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...

Evaluation of Non-Ductile Drilled-in Expansion Bolts
This paper provides background and justification for the design of closely spaced non-ductile drilled-in expansion bolts (bolts). It describes testing used to establish allowable design...

A Strength Criterion for Grade AGOT Graphite

West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...

Possible `Ductility' in a Material with Planar Discontinuities

Brittle or Ductile?

Ductility of Square-Confined Concrete Columns
A brief review showed considerable differences in the quantity of rectangular hoops required by various seismic design codes in the potential plastic hinge regions of rectangular reinforced...

Eccentric Bracing in Tall Buildings
Primary concerns in the design of high-rise buildings, particularly those located in seismically active regions, are the control of interstory drift and the ability of the structure to...

Ductility of Spirally-Confined Concrete Columns
Five large circular reinforced concrete columns confined by spiral reinforcement in accordance with the provisions of the draft of the New Zealand Concrete Design Code were tested under...

Seismic Response of Reinforced Concrete Frames
Analytical studies of the elastic and inelastic response of reinforced concrete frames subjected to earthquake motion are presented. The effect of stiffness degradation on the seismic...

An Evaluation of Inelastic Seismic Design Spectra
After reviewing general methods available for determining seismic design forces for structures which can tolerate limited amounts of inelastic deformations, the reliability of two representative...

Shear Reinforcement for Concrete Slabs
A review of the different types of shear reinforcement for concrete flate plates is presented and the difficulties encountered when these are used in practice are reviewed. Practical shear...

Partial Factors for Structural Damage

Strength and Ductility of Tied Concrete Columns
Short 12-in. (305 mm) square concrete columns with rectangular ties as confinement steel are tested under monotonic axial compression to failure. Land-deformation curves are presented....

Strong and Tough Concrete Columns for Seismic Forces
Design procedures for reinforced concrete columns subjected to seismic forces are presented. Four types of column configurations are considered. The four types are: (1)The ductile moment...

Space Truss Studies with Force Limiting Devices
Experimental test results are presented of the use of force limiting devices (FLD) on the compressive chords of two-layer space trusses. Two subassemblages and one full-scale truss were...

Seismic Design Criteria for Underground Pipelines
The current design practice for water/sewer lifelines does not take seismic loads into account. Note that the design of buried pipelines for seismic excitation is not necessarily governed...
