Created by engineers for effective engineering, SAP2000 is the ideal software tool for users of any experience level, designing any structural system. An additional suite of advanced analysis features are available to users engaging state-of-the-art practice with nonlinear and dynamic consideration. The SAPFire ® Analysis Engine integral to SAP2000 drives a sophisticated finite-element analysis procedure. Basic and advanced systems, ranging from 2D to 3D, of simple geometry to complex, may be modeled, analyzed, designed, and optimized using a practical and intuitive object-based modeling environment that simplifies and streamlines the engineering process. SAP2000 is general-purpose civil-engineering software ideal for the analysis and design of any type of structural system.

A tie line usually fulfill a dual purpose i.e.This space is devoted to SAP2000.A tie line is a line joining fixed points termed as Tie station on the main survey lines.Thus there is a complete check on the field measurement as well as on the accuracy of the plotting work.A check line is measured to check the accuracy of the framework.A check line also called proof line is a line joining the apex of a triangle to some fixed point on the opposite side.It should be correctly measured and should be measured twice or thrice.It should be laid on level ground, as possible through the center and length of the area.It is the most important line because it fixes up the direction of all other lines, since on base line, is built framework of a survey.The longest of the chain lines used in making a survey is generally regarded as Base line.The sides of triangle should pass as close to the boundary as possible.Īlso See: Types of Surveying Chains Base Line.Position of survey lines should be such that to avoid obstacles to chaining and ranging.Survey lines should be as few as possible.A check line should be provided in each triangle.If possible, line through the whole length of area should be drawn.Main principle of chain survey should strictly be observed.The stations should be mutually inter-visible.The following points should be kept in mind while selecting a station:
