Abstract: The purpose of this study is to analyze the visual
preference of patterns in pedestrian roads. In this study, animation was
applied for the estimation of dynamic streetscape. Six patterns of
pedestrian were selected in order to analyze the visual preference. The
shapes are straight, s-curve, and zigzag. The ratio of building's height
and road's width are 2:1 and 1:1. Twelve adjective pairs used in the
field investigation were selected from adjectives which are used
usually in the estimation of streetscape. They are interesting-boring,
simple-complex, calm-noisy, open-enclosed, active-inactive,
lightly-depressing, regular-irregular, unique-usual, rhythmic-not
rhythmic, united-not united, stable-unstable, tidy-untidy.
Dynamic streetscape must be considered important in pedestrian
shopping mall and park because it will be an attraction. So, s-curve
pedestrian road, which is the most beautiful as a result of this study,
should be designed in this area. Also, the ratio of building's height and
road's width along pedestrian road should be reduced.
Abstract: The paper deals with the analysis of the dynamic
response of footbridges under human - induced dynamic loads.
This is a frequently occurring and often dominant load for
footbridges as it stems from the very purpose of a footbridge - to
convey pedestrian. Due to the emergence of new materials and
advanced engineering technology, slender footbridges are
increasingly becoming popular to satisfy the modern transportation
needs and the aesthetical requirements of the society. These
structures however are always lively with low stiffness, low mass,
low damping and low natural frequencies. As a consequence, they are
prone to vibration induced by human activities and can suffer severe
vibration serviceability problems, particularly in the lateral direction.
Pedestrian bridges are designed according to first and second limit
states, these are the criteria involved in response to static design load.
However, it is necessary to assess the dynamic response of bridge
design load on pedestrians and assess it impact on the comfort of the
user movement. Usually the load is considered a person or a small
group which can be assumed in perfect motion synchronization.
Already one person or small group can excite significant vibration of
the deck. In order to calculate the dynamic response to the movement
of people, designer needs available and suitable computational model
and criteria. For the calculation program ANSYS based on finite
element method was used.
