The objective of this article is to present the results obtained in a study on the interaction between the behavior of the structure and the foundation settlements and verify the influence of normal load distribution on the columns. In this mechanism, known as structure soil interaction (SSI), as the building is constructed, a transfer of loads occurs from the columns which tend to settle more to those that tend to settle less. The study was conducted in a building which had its settlements monitored from the beginning of construction. For this purpose, a linear tridimensional numerical model was constructed and numerical analysis was performed, using the finite elements method. In these analyses, numerical models corre- sponding to the execution of each floor were used, considering the settlements measured in each stage of the construction. The results of analy- ses showed that the effect of SSI are significant for calculating the normal efforts on the columns, particularly on those located in the first floors.

Abstract This paper describes a visual simulation tool for reliable off-line development, verification and debugging of the control code of the Programmable Logic Controller (PLC) in the sequence control system. First, we discuss the uniform modeling method of the dynamic behavior of various components in a factory (actuators, sensors, operating panels, etc.) as the object model and state transition model. Then we propose the implementation method of the object model by VRML and JAVA. They enable us to uniformly describe the state-transition and corresponding dynamic behavior of the 3-D geometry of each object model. Moreover, we can use a standard VRML viewer which has the event-driven execution mechanism as a visual simulation tool. The effectiveness of proposed implementation and simulation is confirmed through the case study on the co-simulation of combining the component model with a real PLC.
