BUCKLING OF
METAL PLATE CONNECTED JOINTS. Ahmed Elragi and George Kyanka, Faculty of Construction

In recent years, the use of metal plate connected trusses
has expanded to cover residential, commercial, industrial buildings uses. Large span
trusses are widely used. Members of such trusses experience forces of high values. Large
metal plate connectors are used to transfer these forces. Buckling of the unsupported area
of the metal plate connectors will be one of the failure criteria of such trusses.
This study investigates the buckling behavior of the
unsupported area of metal plate connectors of different types of joints. This includes
single and double web joints, square end web and fitted end web joints. The effect of
changing the angle between the web and the chord members is also studied. The study was
performed numerically and was verified experimentally.
Results show that buckling of the unsupported area of metal
plate connectors is a main reason for joint failure. The buckling load depends on the
joint configuration. The angle between the web and the chord members affects the buckling
load. For large metal plate connectors the buckling load is the same for both square end
web and fitted end web. In this case buckling occurs in the area between the web and the
chord members. Buckling load can be increased by increasing the metal plate thickness.
A CONSTRUCTION PROJECT MANAGEMENT TOOL- PRIMAVERA PROJECT PLANNER.

Primavera Project Planner (P3) is a software
package that is designed to aid in the management of projects and project schedules. P3 accomplishes this by being used individually or in conjunction with other software
packages such as Expedition, SureTrak, Microsoft Word, PowerPoint, and Excel to name a
few.
P3's main advantage is to manage multiple
projects simultaneously. P3 will accept projects from SureTrak as well as other
P3 created projects. P3 has the ability to link schedules together
to form one master schedule. Project resources, costs, activities, and progress can be
tracked, monitored, and updated. Information can be shared with coworkers through e-mail
and may be "Access Rights" protected.
P3 has many features, several which are displayed
here. Projects may be grouped, sorted, and filtered in a variety of ways to show details
of the project more specifically. Calendars may be changed or created to meet the needs of
a particular project. P3 has a variety of predetermined layouts or allows to
you to create your own for printing reports and schedules. The P3 allows for
viewing a schedule in an Activity on Node format as well as the standard Bar Chart format.
Constraints and milestones may be added when an activity or resource is a critical issue
on the schedule or when certain dates must be met. |
