Abstract
The safety of designed urban structures is highly depending on the respond of structures to different types and magnitude of environmental loads. The safety assessment of an existing building needs to have a full consideration of all the environmental factors. Therefore, the engineers must realize the importance of the environment and take care of all the assumptions and uncertainties. One of the hot topics that researchers nowadays are interested is the influence of climate change to the engineering designs. There is a remarkable consensus in the scientific community telling us a fact that our climate is changing and engineering design failures are increasing. In this paper, we are going to have an investigation of the effect of the climate change to the safety of high rise building. The climate effects are briefly discussed at the first beginning of this paper. Then a detailed study is performed on the modeling of climate effects for the wind load. This is later utilized in a structural reliability analysis for a high rise building. The influence of climate effects to the overall safety of a building is investigated and discussed based on the analyzed results. It was found the influence of climate effect can be very significant in the design of high rise buildings.

Climate provides the human beings the context of environment which is suitable for us to live in this planet
We will do a reliability analysis for a simple engineering problem based on code BS6399 and try to see the influence of climate change on the high rise building’s reliability
In Florida State, it has used a specified 50-year nominal design wind speed of 49.17 m/s for their design due to the ASCE Standards 7-93 [16]. This extreme wind speed should be selected based on probabilistic approach which could make sure the occurrence of it is rather small during its time interval
Summary
Climate provides the human beings the context of environment which is suitable for us to live in this planet It contains several key factors in our ecosystem including the air, temperature, water, and wind. Over the last 150 years, the CO2 concentration has increased by 30% and the CH4 concentration has increased by 150% globally [1] These atmospheric changes together with human-induced natural influences have changed the climate. We are going to explore the influence of climate change to the safety of high rise building. We will do a reliability analysis for a simple engineering problem based on code BS6399 and try to see the influence of climate change on the high rise building’s reliability.
