the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...

A mix design, using a mixture of sand and mine tailings as aggregates, was selected to produce cement-based 3D printing material suitable for building purposes. Different dosage rates tailings, water, superplasticizers, accelerators were added the with end looking optimum strength, workability buildability. The term buildability includes aspects such pumpability printability. tests carried out ...

In this paper, we present techniques combining intensity and range data to achieve more realistic three-dimensional models from real world scenes. The principal novelty is the use of the intensity information not only for texturing the final 3D model but also to improve the segmentation of the range data. The technique registers video and range, i.e., the camera parameters are computed in order...

We present a concept for combing 3D models and multiple heterogeneous sensors into a surveillance system enabling superior situation awareness. The concept has many military as well as civilian applications. A key issue is the use of a 3D environment model of the area to be surveyed, typically an urban area. In addition to the 3D model, the area of interest is monitored over time using multiple...

This article presents the animated visual 3D programming language SAM (Solid Agents in Motion) for parallel systems specification and animation. A SAM program is a set of interacting agents synchronously exchanging messages. The agent’s behavior is specified by means of production rules with a condition and a sequence of actions each. Actions are linearly ordered and execute when matching a rul...

This paper presents a new approach for 3D human walking modeling from monocular image sequences. An efficient feature point selection and tracking approach has been used to compute feature points' trajectories. Peaks and valleys of these trajectories are used to detect key frames—frames where both legs are in contact with the floor. These frames, together with prior knowledge of body kinematics...

The main aim of the present study is to achieve optimum design of reinforced concrete (RC) plane moment frames using bat algorithm (BA) which is a newly developed meta-heuristic optimization algorithm based on the echolocation behaviour of bats. The objective function is the total cost of the frame and the design constraints are checked during the optimization process based on ACI 318-08 code. ...
