Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

Redundancy Evaluation of Existing Bridges
The redundancy of an existing bridge can only be correctly assessed by considering the full superstructure as a single entity. Any formulation based on the analysis of bridge components...

Calibration of a Bridge Rating Formula for Overload Permits
This paper proposes a method to calibrate a reliability based load and resistance factor design (LRFD) permit evaluation formulation that will account for the overloaded truck's...

LFRD Bridge Design as Viewed by the Designer
The load and resistance factor design (LFRD) design concept has been resisted by some bridge engineers on the grounds that it represents a reduction of the 'factor of safety'...

Multiple Presence Reduction Factors for Bridges
This paper reviews the multiple presence reduction factors specified in the AASHTO and Ontario codes, and provides a method by which these factors can be established in relation to volume...

Overview of the Guidelines for T/L Structure Loadings
This section introduces a reliability based design methodology that forms the framework for the loading guidelines. A Load and Resistance Factor Design (LRFD) format is presented for the...

Steel Plate Girder Alternate I-10/I-17 Interchange
The scope of the Phoenix I-10 Viaduct allowed extensive study for the optimization of this moderate span steel plate girder bridge. The value engineering studies lead to the use of the...

Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...

Evaluation and Surveillance of Concrete Bridge Structures
A number of cost-effective techniques are available for evaluation and surveillance of concrete bridge structures. The methods covered in this paper include: long-term bridge instrumentation,...

Feasibility Studies of Flood Warning-Response Plans
Local flood warning-emergency preparedness plans consist of hardware, technical activities, and formal and informal inter- and intra-organizational arrangements and commitments to performance...

Overview--Committee Report on Dam Safety Guidelines
In November 1984 the Surface Water Hydrology Committee appointed a task committee with the assignment to suggest standards for the hydrologic safety design of dams. The committee report...

Criteria for Spillway Design Floods
The procedures outlined in this paper only address the hydrologic safety criteria for spillway design floods. The recommended procedures are based on a careful identification of the social,...

Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...

Dynamic Behavior of R/C Buildings in Vi? del Mar, Chile
The Chilean earthquake of 3 March 1985 resulted in an effective peak acceleration of 0. 36g in the coastal city of Vina del Mar. The city had an inventory of over 400 reinforced concrete...

Unusual Shaped Highrise Buildings in Seismic Zone
The structural concepts, seismic analysis and design of five recent highrise structures are presented in this paper. The paper deals with the problem of multistory buildings having 'structural...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...

Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...

Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...

Behaviour of Thin-Walled Channel Sections in Bending
The effects of local buckling on the behaviour and load carrying capacity of thin-walled cold formed steel plain channel sections is examined. The bending is applied in such a way that...
