Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...
Inelastic Seismic Design of Concrete Structures
This paper provides an overview of the state-of-the-art publication on the same subject under preparation by ASCE-ACI Committee 442's Ad Hoc Subcommittee on Inelastic Response...
Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...
Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...
Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...
Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...
The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...
Pressuremeter Evaluation of Glacial Till Bearing Capacity in Toronto Canada
Glacial tills were evaluated at three Toronto sites, using conventional methods, the pressuremeter and full scale caisson load tests. The geologic environment and specific subsurface conditions...
An Evaluation of Pile Design in Fraser River Delta Using In-Situ Tests
Modern methods of pile design often take advantage of in-situ test data. Thirteen axial pile capacity design methods have been evaluated using the results from eight full-scale pile load...
Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...
First-Order Estimation of Ko in Sands and Clays
The in-situ horizontal stress coefficient (Ko) is known to be the dominant design parameter controlling the side resistance of deep foundations....
Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...
Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...
Settlement Characteristics from Insitu Tests in Flyash Structural Fills
Flyash from the Baltimore Gas and Electric Company's plants was used to construct structural fills in thickness ranging from 5 to 25 feet (1.5m to 7.6m). Several warehouses...
Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...
Model Tests for Bearing Capacity of Vertically Reinforced Foundations in Sand
Laboratory model test results for the bearing capacity of strip foundation supported by a sand layer with semi-flexible vertical rod reinforcements have been presented. All test results...
Tangent Modulus of Piles Determined from Strain Data
When evaluating measurements of strain or telltale shortening of a pile subjected to loading test, precise knowledge of the 'elastic' modulus is necessary. By means of plotting and analyzing...
