Prestressed Concrete Failures Due to Uplift
The paper presents some examples of prestressed concrete DOUBLE-TEE (DT) failures caused by hurricane Andrew. The DT's failures was mainly due to the negative moment created by uplift....

Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...

Cyclic Performance of Riveted Connections
As part of a larger experimental project on seismic performance of older steel frames, seven concrete-encased and unencased connections were tested. The specimens consisted of both riveted...

Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...

Seismic Retrofit of R/C Columns with Inadequate Lap Splices
This paper presents experimental results on the use of rectangular steel jackets to improve the seismic performance of rectangular steel jackets to improve the seismic performance of rectangular...

Design and Analysis of the 712 Fifth Avenue Structure
New York City's 712 Fifth Avenue is an extremely-slender concrete tube tower. This text addresses the structure's lateral structural system, wind analysis, computer model, thermal analysis...

The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...

Damage Prediction in Reinforced Concrete Structures under Cyclic Loading
Assessment of the stiffness, resistance and damage behaviour of reinforced concrete members under high cyclic loading due to earthquake actions must consider material nonlinear effects...

Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...

Research of Strength and Deformations with Long-time Loading and the Use of Glassfiber Reinforced Concrete in Shells
Presented is an experimental research on the properties of behavior on compression and tension of glassfiber reinforced concrete of alkali-resistant glass fiber under long-time load and...

Project Case Study: Space Frame Roof Structure, Main Stadium, Shah Alam Sport Complex, Selangor, Malaysia
In the city of Shah Alam located just outside of Kuala Lumpur, the Shah Alam Sport Complex is built as a multi-use sports facility. The aim of this study is to discuss the management of...

Concrete Shells Today
Providing high structural qualities, modern shells using experimental forms will attract new attention due to their limitless repertory. Presented is a new form of construction, instead...

Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...

Study on Reinforced Concrete Cylindrical Shells with Edge Members under Impact Loading
The strength, cracking patterns and the other nonlinear dynamic behaviors of reinforced concrete roof-type circular cylindrical shells influenced by edge member stiffness and supporting...

Nonlinear Analysis of a Reinforced Concrete Folded Plate Structure
This paper deals with the ultimate load analysis of a reinforced concrete (RC) folded plate shell subjected to dead load and monotonically increasing live loads, statically applied, using...

Spatial Structures Erected out of Thin Shell Elements Fabricated on Plane Followed by Bending
The paper offers the examples of spatial structures of average spans (up to 24 m) and engineering structures made of prefabricated curvilinear elements originally having a plane form....

Ultimate Strength of R/C Cooling Tower Shell
Reinforced concrete(R/C) cooling towers are the largest, thin shell structures. It is important to assess the ultimate strength of R/C cooling tower shells subjected to wind load. In the...

Repair of a Cracked Cooling Tower Shell Based on Numerical Simulations
The present condition of a 30 years old cooling tower shell made of reinforced concrete is characterized by a relatively large number of long, thermally induced meridional cracks. For...

Design for Durability for Large Reinforced Concrete Shells
Classical design concepts restrict themselves to sufficient structural safety, using linear analysis methods. Durability questions are mainly treated independently. Modern computer simulations...

Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...
