The experimental test program being conducted at the National Institute of Standards and Technology on 1/3-scale model precast concrete beam-to-column connections is summarized. The objective...

Seismic Response of Average High-Rise Building Structions in Japan
Dynamic characteristic models, representing average high-rise building structures in Japan, have been established through the regression analyses utilizing review documents of seismic...

Safety Enhancement of Bridges with Seismic Isolation Bearings
This paper summarizes the experimental and analytical studies done at Dept. of Civil Eng., Kyoto Univ., on application of base isolation bearings to highway bridges and the Menshin (base...

Seismic Collapse Assessment of Reinforced Concrete Building
In this paper collapse analysis of reinforced concrete frame structures with and without brick infilled walls under a severe earthquake is developed. Because the structural element in...

Large-Scale Earthquake Simulator Study of the Tohoku University Base-Isolated Building
This paper describes a series of earthquake simulator tests of a 1/2.5-scale, base-isolated, three-story, reinforced-concrete building. Three different types of elastomeric seismic isolation...

Data Base for Seismis Rick Assessment in Mexico City
We describe a model to estimate expected ground motions and expected damage, based on intensity damage relations derived for 14 classes of buildings representative of Mexico City construction....

Earthquake Resistant Design and Construction of Reinforced Concrete Buildings. The Practice in Mexico After 1985
The evolution of the design and construction practice of reinforced concrete buildings in Mexico is presented in terms of materials, structural systems, member design and reinforcement...

Damage Assessment for Reinforced Concrete Buildings with Shear Walls
This paper tries to establish the analytical method of damage assessment for R.C. buildings with shear walls before or after earthquake. Incremental nonlinear spectrum analysis, using...

Welded Wire Confinement Grids
The invention of a new way to reinforce concrete using high strength welded wire grids, (WWG) increases its earthquake resistance by improved ductility and also opens the way for vast...

Seismic Strengthening of R/C Columns Using Steel Jackets
This paper presents experimental results on the use of steel collars and steel jackets as a retrofitting system to improve the seismic performance of short rectangular reinforced concrete...

Use of Eccentric Steel Bracing for Strengthening of R/C Frames
This paper presents preliminary results of ongoing research investigating the feasibility of steel eccentrically braced frames (EBFs) for seismic retrofit of reinforced concrete frames....

Code Provisions for Unreinforced Masonry Bearing Wall Buildings in California
Prior to the Long Beach earthquake of 1933, unreinforced masonry (URM) construction was usual in California, as it still is in many areas of the United States. The poor performance of...

CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...

Earthquake Strengthening of a Twelve Story Non-Ductile Concrete Frame Building with Unreinforced Masonry Using Displacement Control Criterion
The structural concern with the Cooper Arms Apartment building when subjected to ground shaking was the in-plane and out-of-plane forces on the infill and consequences of the infill resisting...

A General Hysteresis Model for Wood Structures
To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model...

Fire Retardant Treated Wood
The paper explains how FRTW chemicals react with combustible gases. It describes the two types into which FRTW is divided. Misconceptions about FRTW are also addressed....

Fire Endurance Model for a Metal-Plate-Connected Wood Truss
A numerical model has been developed for predicting the fire endurance of a single metal-plate-connected wood truss. Extensive component fire testing was conducted to develop the necessary...

Investigation of a Failed Concrete Joist System
The failure and distress of concrete joists contained in the promenade roof deck of a one-story, college, lecture hall building initiated an extensive investigation to determine the cause...

The Effective Use of Fire Ratings
Any consideration of components for construction must take into account the performance of those components when they are exposed to fire. Codes, standards, and fire ratings provide some...

Things That Fall?Lessons from Some Construction Accidents and Structural Failures
The causes and results of several construction accidents are reviewed. The lessons to be learned from such a summary are that all too often the simplest oversight leads to catastrophic...
