Adaptive kinetic architecture has emerged from a need for innovative designs that adapt to the\nenvironment and changing needs of the occupants. Architectural design and modes of egress are critical\nin an emergency. Flocking describes a certain collective behavior where agents are brought together\nin groups and move as a cohesive unit from place to place. Collective behavior may be observed in\nmicroscopic as well as macroscopic environments. Crowd modeling incorporates the study of human\nbehavior, mathematical modeling, and molecular or fluid dynamics. The simulation of agents and\ntheir movement in the built environment is beneficial for design professionals, scientists, and engineers.\nHuman behavior in panic situations is notably similar to fluids and molecules. The objective of this\nresearch was to evaluate the movement of agents in buildings using discrete dynamic simulation. We used\na novel discrete molecular dynamics technique to simulate the evacuation of agents in panic situations.\nVarious adaptive geometric configurations were analyzed for improved crowd flow. Kinetic walls\nwere modeled in order to evaluate design optimization as it relates to rates of egression. This research\nproposes the use of kinetic walls to improve safety and efficiency during an emergency evacuation.\nAdaptive geometric configurations show improvements over the conventional design framework....
With the aim to model the seismic behavior of steel reinforced concrete (SRC) frame\ncolumns, in this research, hysteresis and skeleton curves were obtained based on the damage test\nresults of SRC frame columns under low cyclic repeat loading and the hysteretic behavior of the frame\ncolumns was further analyzed. Then, the skeleton curve and hysteresis loops were further simplified.\nThe simplified skeleton curve model was obtained through the corresponding feature points obtained\nby mechanical and regression analysis. The nonlinear combination seismic damage index, which was\ndeveloped by the test results and can well reflect the effect of the loading path and the number of\nloading cycle of SRC frame columns, was used to establish the cyclic degradation index. The strength\nand stiffness degradation rule of the SRC frame columns was analyzed further by considering the\neffect of the accumulated damage caused by an earthquake. Finally, the hysteresis model of the SRC\nframe columns was established, and the specific hysteresis rules were given. The validity of the\ndeveloped hysteresis model was verified by e comparison between the calculated results and the test\nresults. The results showed that the model could describe the hysteresis characteristics of the SRC\nframe columns under cyclic loading and provide guidance for the elastoplastic time-history analysis\nof these structures....
Restoration of architectural formation elements is basically trying in estimating\nthe optimization method which places it old architectural artist in his\nwork. The article aims at rooting the methodology of restoration of the architectural\nformation elements. It is essentially intellectual effort by the restorer\nin assessing the best way the artist and the old architect in his work. In order\nto reach the purpose behind this works and analyze the original available\ntechniques in the creation period, the restoration process can be completed as\nfully as possible. The research is concerned with re-confidence in the classical\nmethods in the restoration of buildings as consolidation and reconstruction.\nThe classical method is a real way to restore the building to its original form\nespecially in the availability of all technological tools to achieve reporting and\ndocumentation. It is not necessary to extension in using unapplied materials\nand technique. In this regard, the research was able to provide solutions, ideas\nand techniques that helped preserve and restore elements of architectural\nformation. The research also pointed to the importance of linking the physical\nand plastic aspects of the archaeological element....
Ammatoa Kajang vernacular houses are buildings that have existed for a hundred years\nas residential house buildings. These traditional houses are unique in their use of bent piles. This\nresearch examines the strength of the structural system of Ammatoan vernacular houses based on\nsaid houses' ability to adapt to various environmental conditions and natural phenomena. This\nstudy seeks to enrich these studies by examining the specific structural strength of these buildings.\nIn the face of modernization and extreme climate change, the continued existence of such traditional\nhouses has been threatened. Disaster may strike at any time, and as such we must explore the\nstructural strength of their structures to predict these buildings' ability to endure such events. This\nresearch applies an interpretative model to explore the structural system, using a load test to\nexamine the houses' structural strength. Although such a model assumes that each building has the\nsame pitch, each house has its own pitch. Therefore, the measurement results cannot be applied\ngenerally to describe the structural strength of every Ammatoan house. This research also notes that\nthe pin joint system, material selection, and application of a grounded foundation are factors that\npromote these buildings' continued endurance and ability to withstand earthquakes....
This paper investigates the stability of a rectangular tunnel face affected by surcharge loading in soil with a soft upper layer and\nhard lower layer using upper-bound finite element methods with a plastic-dissipation-based mesh adaptive strategy (UBFEMPDMA).\nSeven different positions for the soil interface are selected to study this problem. The upper bounds on the ultimate\nsurcharge loads...................
