FOREST IN THE CONCRETE JUNGLE

Fall 2022

Focusing on the needs of places for elderly people, teenagers, office workers and young artists in Shenzhen, we try to create a place where people can rest, talk, walk, entertain and display themselves in the big city, and put forward the need for a landmark building that can feel the natural atmosphere in the concrete jungle.

According to the site conditions and the needs of specific materials, the design innovatively uses the tensile properties of wood to develop a structural type that uses reticulated concrete beams to bear the load and suspends the floor through wooden strips, and adjusts the traffic mode and plane layout of the building to form a place suitable for different people.

Forest In The Concrete Jungle

The metropolis is full of airtight concrete buildings. People are eager to find nature in the concrete jungle. Wooden structure has comparatively characteristics of light weight, environmental protection during construction, convenient installation and disassembly, and strong recyclability. Although it cannot be used in large quantities, it can be seen as a symbol in the city. As a rest place with good air circulation and lighting, it brings people with natural atmosphere, and makes them get out of the busy city for a moment of rest.

Mechanical Properties Of Wooden Materials

The conventional wooden structure has a relatively small span, which cannot meet the requirements of opening to traffic on the ground floor.

Generation

It has good tensile properties along the longitudinal direction of the wood. Inspired by this, the load of the floor can be transferred to the grid beam system by the wooden strips, that is, the structure can be "hung up" by the beam system. VERTICAL TRAFFIC SYSTEM SUSPENSION

In order to make it more comfortable for the elderly, the vertical traffic mode has been designed as a gentle slope with a gradient of less than 10%.

Variable Layout

The hanging system of the structure plays a role through the tensile performance of the wooden strips. The continuity of the strips determines that as it moves from top to bottom, the strips used for hanging on each floor will gradually decrease, which means an increasingly wide space pattern will be formed from top to bottom. According to the characteristics of this type of structure, the plane layouts are adjusted to form to suit for different people. Unlike ordinary structural types, the top reticulated beam system bears most of the load, so the strength of steel-wood joints is particularly important.
