Reliability-Centered Management of Wood Transmission Lines
Through implementing reliability-centered management concepts, more cost-effective management of wood pole transmission lines may be achieved. By identifying individual structures and...
Reliability Consideration in Shakedown Analysis
Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual...
Reliability of Nonlinear Frame Structures by SFEM
A method is proposed for the reliability analysis of nonlinear frame structures with flexible connections. The uncertainty of a connection is represented by a group of random moment-relative...
The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...
Crane Raise with Zero Downtime
Massachusetts Fort Authority (MPA) was faced with a dilemma. Its Conley Terminal tenants needed higher cranes but could not relinquish the cranes for more than a few days at a time. No...
Upgrading Today's Terminals for Tomorrow's Needs
This paper describes how a 1940's vintage, timber pile supported wharf is being modernized to serve post-Panamax ships: how the Massachusetts Port Authority (MASSPORT) is rebuilding their...
Historic Seawalls of the Boston Harbor, Massachusetts Region: Evolution, Construction and Repair
The earliest seawalls in the Boston region were of crib construction. Cobb cribs had an open framework and could readily be floated into position and sunk with rock from local sources....
Nonprestressed and Prestressed FRP Sheets as External Reinforcement of Wood Members
The paper presents a summary of an analytical and experimental investigation of a new form of wood construction involving external bonding of thin fiber reinforced plastic (FRP) sheets...
Structural Performance of Hardwood-Metal Composite Beams
This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges....
Earthquakes: A New Look at Cracked Masonry
Economics, fears of liability, and a strict damaged-buildings repairs ordinance have contributed to an extensive delay in the repair of masonry-infill buildings in earthquake-stricken...
Snow Fence Operational and Material Testing
The proliferation of snow fence products since the late 1970's presents an opportunity for optimizing the control of drifting snow. It also presents a challenge in discriminating...
Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...
Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....
Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
Discrete Optimal Design of 3D Frameworks
The paper describes a discrete optimization method for the least-weight design of three-dimensional (3D) steel building frameworks. The method involves the coordinated application of structural...
Strategies Which Permit Multiple Discrete Section Properties per Member in 3D Frameworks
Strategies for discrete structural optimization of 3D steel frames with coupled section properties are presented. These strategies include linearized branch and bound, simulated annealing,...
Optimization of RC Frames with Reliability Concepts
Analysis and design optimization are considered simultaneously for reinforced concrete frames. Global displacements were considered as design variables. The nonlinear behavior of the elements...
Data Modelling for Steel Frame Structures
The first step to automate any facet of structural engineering is developing a suitable data representation upon which the computer program will operate. However, there is no standard...
A Substructuring Algorithm for Analysis and Optimization of Large Structures on Parallel Machines
An efficient substructuring algorithm is presented for analysis and optimization of frame structures on parallel machines. The underlying concept is to pre-process the input data in such...
