Preferred Abstract (Original):

In recent years, the utilization of computer techniques in engineering application has become an irreversible trend. This is achieved through using computer as the device for modeling, analysis, and design. The study mainly has focused on

the accuracy of the tributary area method for estimation load , as compared to finite element method by SAP2000, considering the effect of building overall height (i.e. number of storey's) from 1 to 10 and column dimensions (i.e. stiffness) from 20×20 cm to 70×70 cm. According to the analysis of the data obtained, we can see the error in the load

computed by the tributary area approximation becomes relatively larger as the number of storey's increases, especially for the ateral load calculations, and the stiffness of the columns increases, the predictions using the tributary area method improves for both axial and lateral forces in the columns.

Preferred Abstract (Original):

According to the ACI building code, the concrete slab can be divided into two types depending on the ratio of the long side to the short side. Regarding the results of the ratio, the concrete slab can be divided as one-way and two-way slabs. The main objective of this paper is to study the stress or moments distribution in solid slab panel in its two directions and compare with ACI code assumption that the load is transferred mainly in short direction and most of the load is transferred in one direction only if the ratio of the longer span to the shorter span is greater than one. This will be discussed by analyzing one panel of solid slab using the computer software SAP2000. Two types of panels will be used; the first one a panel that is supported simply on its four sides and the second panel is supported only by four pin supports and beams. This paper shows that the gravity load on the slab is transferred to long and short direction. This means that one-way concrete solid slab doesn't exist and all concrete solid slabs work as a two-way concrete slab.

Preferred Abstract (Original):

This research is an attempt to understand the distribution of axial loads on columns in one story building model under different case of slab (rigid and flexible slab) and different load condition (gravity and horizontal load), then comparing the results obtained by model with those results obtained by tributary area method. To do this, a technique utilizing finite element analysis is used in order to create computerized model with SAP2000 program. This model is built to simulate the real state of slab and columns in one story building. According to the analysis of the data obtained, we can see the big difference between the real load carried by columns and the load calculated by using the Tributary area method, so using 3-D model is the best method to calculate the real load effected on columns and design this columns according this load.
